With our expertise in consultancy, technologies and services, we help to design the best blends that meet our clients' demands. For more than 70 years DMT has been collecting data from steel coke inspections, coal blend carbonization tests and coking processes, which are done in parallel in different scale coking environments.
Coke has high carbon content and few impurities acts as a fuel for iron making process. It is the solid carbonaceous material derived from destructive distil-lation of coking coal.
Mineral beneficiation is a process that seeks to improve the quality and value of ore by cleaning and purifying it. Impurities and other contents are separated to achieve a higher purity of the ore or coal and prepares it for further processing. ... Our experience in coke-making is exceptional and we provide a comprehensive range of services ...
Efficacy of Pilot Scale Batac Jig on LVC Coal Utilization for Coke Making. Transactions of the Indian Institute of Metals 2023-06 | Journal article DOI: 10.1007/s12666-023 ... Beneficiation of difficult-to-wash Indian low volatile coking coal …
The blast furnace route of iron making is predominant in India. Blast furnace (BF) process of iron making is a process where liquid iron (hot metal) and liquid slag are produced by the reduction of iron-bearing materials (sinter and/or pellet and lump ore) with coke and by fluxing of the gangue material of the feed materials (IBM 2011). …
coke fines are generated during the coke . making, and iron ore fines are gen. erated during mining of iron ore. Although iron ore fines are used for making pellet after beneficiation . still, it generates a . huge. quantity of iron ore waste during beneficiation with comparatively lower iron content. In the present study, briquettes are . made ...
We produce steel through the conventional blast furnace route. Raw materials are converted to hot metal and crude steel through various processes including coke making, sinter making and pelletisation. The processes are designed to deliver high productivity with the available resources while managing slag rate and steelmaking requirements.
Distribution of mineral matter in coking coal plays a significant role in achieving the desired product for blast furnace and coke-making operations. The present paper reports a case study on the distribution and nature of mineral matter in Indian coking coals at varying densities with respect to the coal's beneficiation behavior.
Raw material preparation – During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. The dried material is fed to the ball mill for grinding. ... decomposition of carbonates and hydrates takes place. Gasification of solid fuels like coal or coke and conversion of iron ...
Abstract The coal blends are used for both top and stamped charged coke oven batteries in Steel Plants which are consists of more than 5 to 7 individual coal sources depending upon the availability of coking coal. The blast furnace (BF) coke produced from the coke oven batteries are feed into both small and larger BF. The consistency of coke …
The beneficiation techniques adopted for washing thermal coals are much simpler and easier to operate than the metallurgical coals. Generally, froth flotation is not employed for treating the fine fraction of thermal coals, which evades the requirement of associated pumping and feeding …
† Anthracite coal for additives in the steel making industry † Beneficiation of PRB coals † Metallurgical grade bituminous coals used in making coke † Beneficiation of lignite coals † Bituminous coals used in direct steel making processes † Lignite coals prior to gasification or liquefaction such as the "Corex" process
Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques …

Beneficiation of a high-ash (35%) medium coking coal to obtain a low-ash (12%) clean coal product is investigated. ... which is the specific property required in order to make coke suitable for making steel. Coke quality is largely influenced by coal rank, composition, mineral content and the ability to soften when heated, become plastic, and ...
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite [].Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about 7% to below 3%, …
