KEYNOTE LECTURESTechnological Advances in Meeting the Challenges of Provisioning Metals forSustaining Societal DevelopmentKhanindra PathakProfessor, Department of Mining Engineering, Indian Institute of Technology KharagpurE-mail: khanindra@mining.iitkgp.ac.inTo meet the developmental demands and societal requirements, the demands of metal is everincreasing. However, the demand patterns have changed recently and those of non -conventionalminerals and metals are also increasing. Substitute of metals have impac ted the supply chains.Recycling is facing different challenges. Mining of low-grade deposits and reclaims of tailingsmaintaining safety standards and protecting the environment have induced new techno -economicchallenges. For the higher productivity and safety in various activities in metals’ provisioningunder complex domains of constraints, technological advances are called for.Data driven management, prognostic maintenance, remote and automated operations using AI andIOT have opened new possibilities in the mining and metallurgical industry. Converting waste towealth through advanced technology for enhancing quality of life is being researched anddemonstrated increasingly. At the same time there is also a growing interest in applying ourtraditional knowledge and local solutions for some of the environmental and safety relatedproblems. Evolving simpler solutions with affordable means should also be considered asadvanced approaches for meeting the challenges. A culture of demonstrative innovation andadoption of advanced technology for progressive transformation in the mineral industry will needa new academic curriculum, new skill development approaches and smart and data drivenmanagement.This lecture discusses some global examples and attempts to emphasis on developing a nationallevel road map for sustainable and responsible mining. To this end recommendation will cover,inter alia, the required academic research and educational program for establishing tools andindicators to enhance performances and to ensure that key mining and environmental risks aremanaged responsibly.4

Advanced Modelling and Simulation of Comminution using the DiscreteElement MethodLuís Marcelo TavaresDepartment of Metallurgical and Materials Engineering, COPPE-UFRJ, Universidade Federal doRio de Janeiro, Rio de Janeiro, BraziE-mail: tavares@metalmat.ufrj.brRecent advances in particle breakage modelling, besides microscale population balance models(PBM) and the discrete element method (DEM) now make possible the simulation of crushing andgrinding operations using commercial software. Depending on the type of comminution machinesimulated either embedded breakage is described, or an option is made to describe breakage usingthe specially formulated PBM. In the heart of both resides the Tavares breakage model, which isa suite of mathematical equations that describe the different modes of fragmentation (body orsurface), besides breakage probability, energy-dependent fragment distribution and weakening dueto unsuccessful stressing events. The work presents examples of application of the approach tosimulate ball and stirred mills, besides selected crushers, analysing their throughput, power andproduct size distribution.Process Intensification in the Separation of Fine MineralsKevin GalvinARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of MineralsNewcastle Institute for Energy and Resources, University of Newcastle,Callaghan, NSW 2308, AustraliaThe transition from a carbon to a metals-based economy is creating an unprecedented demand forminerals, and in turn a diabolical process engineering challenge, given the decreasing grade of theaccessible ore, the need to address new and more complex mineralo gy, while reducing theenvironmental footprint.This challenge demands transformational change to the practice of minerals processing, includingthe need for process intensification. This presentation examines recent developments associatedwith the Reflux Classifier to illustrate how it is possible to achieve significant improvement inseparation efficiency, with a significant increase in processing ‘‘speed”. Here, it is necessary tocontrol the forces that act on the particles in new ways to enhance the selectivity and ultimatelythe segregation of the valuable particles from the gangue. The presentation covers both gravityseparation and flotation, exploring the application of forces that exploit differences in particledensity and differences in surface properties within a hydrodynamic medium such as water.5

Bulk Solids in Iron and Steel Making Industry: Storage, Flow and HandlingBin ChenTUNRA Bulk Solids, The University of Newcastle, AustraliaE-mail: Bin.Chen@newcastle.edu.auBulk materials handling operations perform a crucial function in the iron and steel makingindustry. It is important that the storage and handling systems be designed and operated to achievemaximum efficiency and reliability. The purpose of this presentation is to highlight the presentstate of knowledge associated with bulk handling testing and analytical and numerical methods toovercome challenges, e.g. spillage, blockage, and wear. Over the past several decades, muchprogress has been made in the theory and practice of reliable flow properties test procedures andanalytical methods. These aid in the design of bulk solids storage and discharge equipment andoptimisation to allow for increased efficiency, throughput and service life. With the advancementof simulation techniques and computer power, Discrete Element Method (DEM) has been widelyused across various applications to simulate increasingly complex processes and geometries. Theapplication of large-scale DEM modelling has become significantly beneficial in solving iron andsteel making industry problems to improve bulk materials handling equipment design andoperation. DEM parameters calibration approaches and examples of collaborative validationefforts will also be described. A series of case studies of industrial applications will be presented,including analysis of transfer chute material hang-up and rhino horning, wear, and bin and hopperflow.Step One of Improving TailingsMike CookDirector of MINEXXT, Inc. Golden, Colorado, USAThe majority of tailings’ applications utilize thickeners for the final stages of mineral processing;however, operations often fail to recognize that this is also the first critical step in the tailings’disposal process. Operations are continuously under pressure to increase tonnages, improveefficiencies and to reduce operating costs. Incremental increases or changes in feed characteristics,usually result in an increase of solids and hydraulic loading on the thickeners. In most cases, it isto a point where the thickeners fail to meet the targets required for optimal deposition or, forefficient filtration in say a paste or backfill application.Thickeners are often neglected, yet they are the simplest and least expensive piece of equipmentto upgrade. Typical improvements for tailing applications are increasing the underflow densities,improving overflow clarities, reducing flocculant consumption , increasing the volume of6

recovered water, better control, and more consistent performance. Simple and well proven stepsare available to achieve all these improvements and the cost is surprisingly low, especiallyconsidering the short payback period or when comparing it with the cost of a new thickener.This paper highlights the key components within a thickener that can be upgraded, and the latesttechnologies that provide the greatest impact on the performance or accommodate changes inthickener duties. Some examples and results of successful upgrades are provided, along with adescription of what to upgrade, how to upgrade, and what the key benefits of upgrading actuallyare.New Horizons for CO2 UtilizationProf. S. K. KawatraDepartment of Chemical Engineering, Michigan Technological University, 1400 TownsendDrive, Houghton, MI 49931, USACarbon dioxide is a waste gas in nearly all industrial processes worldwide. The generation of CO 2on such a large scale has alarming consequences for th e world. The capture of CO 2 has beenaccomplished using amines, sodium hydroxide, or sodium carbonate scrubbing operations. Thequestion that comes next is, what do we do with all the CO 2? Much research has gone into findingways to either sequester CO 2 in the ocean or underground, but these methods only contain astockpile of CO2 and are costly rather than profitable. Research into the effective utilization of CO2is far more appealing to industry because it generates profits from the creation of useful products.Michigan Tech has studied the conversion of CO 2 into more useful materials via an electrochemicalconversion. Products such as syn. gas, ethanol, and oxalic acid among others may be produced.Oxalic acid has an important application in mining for the extraction of rare earth elements fromother waste materials like aluminium process waste (red mud). The future of carbon dioxide liesin the ability to produce valuable materials from a waste gas.7

ORAL PRESENTATIONSImplementation of Coal Quality Management System (CQMS) in KathautiaOpencast Coal Mine (KOCCM)Rahul Mitra 1, Arunabha Duari21Assistant Manager(Geology), Hindalco Industries Ltd.2DGM (Geology), Hindalco Industries Ltd.E-mail (in order): rahul.mitra@adityabirla.com, arunabha.duari@adityabirla.comKOCCM of M/s. Hindalco Industries Limited belongs to Daltanganj coalfield. Rajhara -B andPandua Top are the two main mineable seams of KOCCM with an average GCV of 5200 kCal/kg.The most salient feature of this coal is higher GCV with high total moisture ( 25%) due torelatively higher surface moisture ( 18%) of that coal. A coal quality management system(CQMS) has been developed (1) to optimise the coal production, (2) to reduce the landed cost, and(3) to increase the net heat value of coal during burning. Broadly CQMS is subdivided into (1)mining process management, (2) stockyard management, (3) loading & transportationmanagement and (4) coal sampling & assessment of quality management. Within these, miningprocess management is the key process to control and improve coal quality. Blasting is done onlywithin the coal seam to reduce contamination from roof and floor. Before drilling and blastingbench top properly cleaned and after blasting in coal, shale/stone are removed by selective miningif there is any inter-banded shale/dirt band. Dedicated cleaned dumpers are used to stock coal frompit to stockyard where the coal is stocked for approx. 14 days to reduce the surface moisture.Further the coal is transported to railway siding through dumpers. In all the cases proper care istaken to minimise dilution due to floor material in the stockyard/railway siding. Before loading inwagons, empty rakes are minutely checked to ensure that there are no stones/ shale etc. Based onIS 436, 1964 regular basis coal sampling are being done from mine face, stockyard and railwaywagon. Self as well as 3 rd party coal quality assessment is further being done based on IS 1350(Part-I & II). Strong implementation of CQMS including formation of task force assist to achievethe specific coal quality and stable calorific value as targeted. Therefore, it not only has positiveimpact on strict quality control but also in operational economy.8

Characterization of Suitable Backfill Material and Filling Technique forPumped Slurry Blind Backfilling in Underground Coal MinesRohit Roy 1, Sayantan Chakraborty2, Rohan Bisai3, Samir Kumar Pal4, Veerendra Singh 51MSScholar, Department of Mining Engineering, IIT KharagpurScholar, Department of Mining Engineering, IIT Kharagpur3Assistant Professor, Techno India (Saltlake)4HOD and Professor, Department of Mining Engineering, IIT Kharagpur5Principal Scientist, Raw Materials Research Group, Research & Development Department, TataSteel Limited, Jamshedpur2ResearchE-mail (in order): rohit.roy@kgpian.iitkgp.ac.in, schuckjuciv@gmail.com,rohan.bisai1@gmail.com, pal.smair09@gmail.com, veerendra.singh@tatasteel.comSand is considered as the most optimum material for backfilling but in the recent times, a hugeamount of sand depletion is taking place its excessive use in the construction industry. But, in thesame time, the replenishment is not fulfilled leading to huge sand depletion. In order to overcomethis perilous situation, the use of alternative materials for backfilling purpose is the dire need ofthe hour. This study assesses to find the optimum mix proportions of bottom ash and sand as abackfill material and technique of pumped slurry blind backfilling in underground mines. Differentphysical characterization tests such as granulometry, bulk density, specific gravity, EDX,proximate analysis, moisture content and porosity have been conducted on both bottom a sh andsand individually, and also on the varying mix proportions of bed ash and sand. The different mixproportions of bottom ash and sand is prepared for this study, i.e. 30 % bottom ash to 70 % sand,40 % bottom ash to 60 % sand, 50 % bottom ash to 50 % sand and 60 % bottom ash to 40 per centsand. Pumped slurry blind backfilling has been conducted with prepared mix proportion of bottomash and sand on the laboratory prototype of a mine model and the technique is based on inflowrate, direction of flow and maximum filled up area covered by slurry. From the study, the best andsecond best mixture has found to be 30 % bottom ash to 70 % sand and 40 % bottom ash to 60 %sand on the basis of suitable physical characteristics, smooth flowability, good solid p acking up tothe roof of the mine model, maximum covered volume and minimum compressibility.9

Beneficiation studies of Banded Hematite Jasper ore of Joda region, EasternIndiaRanu Srivastava 1*, Ranjit Prasad 11Department ofMetallurgical and Materials Engineering, National Institute of Technology,Jamshedpur - 831014, India*Corresponding Author E-mail: ranusrivastava157@gmail.com*The present paper describes the beneficiation of the banded hematite jasper (BHJ) ore from Jodaarea, eastern India. The main purpose of this study is to produce a pellet grade concentrate fromthe BHJ ore. The feed sample contained total Fe (36.31%), SiO 2 (46.73%), Al2O3 (0.50%) and lossof ignition (1.05%). Size-wise chemical analysis indicated that the finer fraction contained moresilica and less iron value. Liberation analysis indicated that maximum iron grains were liberatedbelow 150-micron size. Beneficiation studies using various unit operations such as hydro-cyclone,falcon concentrator, Wet High Intensity Magnetic Separation (WHIMS) and flotation etc. werecarried out to up-grade the iron values and to reduce the gangue content. The separation techniqueswere decided based on particle size and properties for effective separation. The Hydro -cycloneoverflow portion contained only 26% Fe with 54% SiO 2 hence, it was rejected. The cycloneunderflow was further subjected in falcon concentrator. It was observed from the data that about40% of solids could be recovered in the falcon underflow, but the grade of concentrate (54.20%Fe) was not as high as required for pellet feed. The Falcon underflow portion was again treated inWHIMS. It was observed from the data that grade of iron could be increased upto 58.16% with ayield of 34.00%. The silica content of this concentrate was 12.83% and finally, Flotation test wascarried out on the WHIMS concentrate. It was observed from the data that the grade of ore couldbe raised upto 62.90% with 9.2% of silica values at a yield of approximately 28.4%.Improving Ball Mill Performance by Optimising the Sizing Cyclone forReducing the Recirculation LoadsRatnakar Bonda 1, Harikrishna M.1, Venugopal M. R. 1, Umasankar Attel1, Venkatesh R.1,Lokendraraj Singh 11JSWSteel Limited, Vijayanagar Works, Bellary District – 583275, IndiaComminution is the major unit operation in any mineral processing plant, which consumes higherpower and consumables. Pellet plants require fine ore particles in their feed (generally less than150 μm with 70 to 80% pass through 40 μm) to maintain the requ ired quality. Due to the10

heterogeneity of raw material, there is variation with respect to the raw material chemicalproperties, hardness, texture, and comminution characteristics. The ball mill operating parameterslike the feed rate, dilution ratio, ball charge, cyclone density, particle separation in cyclone dictatesthe recirculation load in mills. In the present investigation, the impact of the separation efficiencyin sizing cyclone, has been studied with multiple factors. Ball mill and cyclone studie s were carriedout by varying the process variables such as the particle size, bonds work Index, cyclone feeddensity, spigot, mill discharge density, cyclone pressure and mill current were analysed in the ballmill and cyclone. The effect of each variable on the responses on recirculation load and particlesize in cyclone overflow was analysed to quantify the effect of each variable on the response alongwith their order of significance. From this study, individual and interactional effects of parameterson the recirculation load and particle size in sizing cyclone overflow have been assessed. The datahave been used to identify the process optimization at plant scale to reduce the power consumption,recirculation loads 450 % reduced to less than 350% which enhanced production and powerconsumption.Keywords: Iron ore, recirculation loads, optimisation, interactional effects, plant trialRheological Properties of Individual Coals: A Real Time Data used for blendFormulation, Case Study of Rourkela Steel PlantS.

Pradhan 11Researchand Development Centre for Iron and Steel2Rourkela Steel Plant*Corresponding Author E-mail: smisra@sail-rdcis.comCoal fluidity is an important coking property which highly influences the coke quality. Coke qualityis a significant factor affecting blast furnace performance with respect to BF production and cokerate. Coal blends are generally prepared as per the available coals on individual coal data like Ash,VM, and FSI. To understand the effect of coal fluidity on coal blending and thereby the coke quality,studies have been conducted using the industrial scale coals and coal blends. In the present study,beyond the regular coal data, rheological data of individual coals have been used for blendformulation. Coke Ovens at RSP use coal from 8-10 different sources for coke making. Largevariations in incoming coal properties have resulted in corresponding variations in coal blend andcoke quality. The coke quality parameters like average Micum Indices M10 and M40 were 9.3 &77.5 respectively during a trial period of 4 months. Coal characterization and plastometricproperties of individual coal were carried out. Coke quality parameters have been monitoredcontinuously and fluidity testing of individual coal and coal blend were also carried out on regularbasis. After revising the blend composition on the basis of test results, it helped in improvement of11

coke quality parameters like M10 (avg. 9.3 to 8.2) and M40 (avg. 77.54 to 79.4) which got reflectedin reduction in coke rate of Blast furnaces at RSP.Keywords: Coal Blend, Fluidity, M40 and M10CFD Modelling of Flow of Slurry through PipelinesSachinraj D1*, Asim Kumar Mukherjee 1, Abhay Shankar Patra 11R&D,Tata Steel Ltd, Jamshedpur, India*Corresponding Author E-mail: sachinraj.d@tatasteel.comThe flow of non-settling slurries through pipelines are often encountered in mineral processingindustries and the study of such flows is primarily explored using experimental means and Semiempirical models are used for the prediction of the different parameters required in the slurry flow.Assuming the solids in the slurry pipeline as a continuum, the behaviour of the slurry inside a pipecan be studied using numerical modelling techniques. In the current study, the experimental resultspublished by Ekambara (2009) are simulated using CFD modelling. Using a two -fluid Eulerapproach, the flow inside a pipeline for fine silica particles is being simulated using Ansys Fluent2020 R2. The solids were simulated using the kinetic theory of granular solids model. Thesimulations were done in transient mode and the distribution of solids inside the pipeline werecompared with the experimental studies. The effect of different source terms on the distributionand pressure was compared with the experimental results. Among the source terms, only drag andturbulent dispersion were found to have a significant effect on the pipe flow. The drag model usedfor the simulations were the Gidaspow model and the turbulent dispersion was simulated using theLopez de Bertadano model. Using the Lopez de Betradano model, a tuning parameter was foundto be required to be input in the model. The same tuning parameter was found to give goodpredictions for variation in the solid content from 10 % to 45 % by volume for the same pipediameter and slurry velocity.12
