In earlier mechanised opencast mines, processing involved was crushing to required size and separation of various products by dry screening. With the increasing emphasis on cleaner product, wet screening has come in vogue in place of dry screening. Small capacity crushers have now given place to large capacity crushers with improved reduction ratio. From Jaw crushers, mine operations Magnetite Concentrate have switched over to gyratory and cone crushers where closely sized materials are required. Since steel plants are switching over to sinter, iron ore fines are now finding market and full recovery of these fines, classifiers, hydro cyclones and filters are increasingly used. For obtaining iron ore concentrates from low grade ore various processing routes of gravity separation, flotation and magnetic separations are in practice through out the world and India too.
Iron Ore Grinding Process is an optional process which makes preparation for the iron ore beneficiation.China's iron ore grinding process, the majority of two-stage grinding process, a small processing Manganese Ore Concentrate plant to use more grinding process. As a result of new technology fine sieve and then ground in recent years a number of concentrator by two to three paragraphs grinding grinding. Grinding equipment used in general is relatively small.Basically, after grinding using a hierarchical spiral classifier. To improve efficiency, some concentrator Hydrocyclone replace the second spiral classifier.
Very low grade Iron ore cannot be used in metallurgical plants and needs to be upgraded to increase the iron content and reduce the gangue content. A process adopted to upgrade ore is called Beneficiation. Iron ore is upgraded to a higher iron content through concentration. Iron ore is being beneficiated all round the world to meet the quality requirement of Iron and Nickel Processing Steel industries.During washing and sizing of the ore, slimes with less than 0.21 mm size are generated and discarded into the tailing pond. Huge quantity of slimes are being generated in every year during the processing of hematite ore and lost as tailings containing around 48-62% of Fe. This possess great amount of pressure on environment and on conservation issue .
The cleaned coal is dried in centrifuges and a belt filter press. Coarse rejects are crushed and then recombined with the fine tailings for disposal to the refuse fill. All ROM coal production is beneficiated in the coal preparation plant. Approximately 2,000,000 tonnes of cleaned coal is produced annually, with the plant processing about 3,000,000 tons of raw coal annually.To view a larger image of the Flowsheet, click on the text above the Flowsheet
