the effective utilization' of low-grade finely disseminated ores that are abundantly available.The utilization of such reserves' may help to.Maintain anadequate supply of minerals to meet economic and strategic needs of our country. Since the yield of low-grade ores is low,escalation in input cost is inevitable.

India. SHARE. The government's push for beneficiation of 80 percent of low-grade iron ore has evoked mixed responses with some miners saying the move will make iron ore mining an unviable business while others say it will incentivize the sector. The beneficiation process improves the industrial value of low-grade iron ore.

Three quarters of the world's phosphate deposits are of sedimentary origin and 75%–80% of those include carbonate gangue. In this study, carbonate sedimentary phosphate deposits of the Lar Mountains of southwest Iran are studied. These deposits consist mainly of calcite, fluorapatite, quartz, kaolinite and illite, with an average P2O5 grade of 9%–10% (low-grade). Various pre …

The cleaning of low-quality coal (coal beneficiation) by using physical and chemical methods has been studied since long back, however there is a need for the advanced and non-toxic process for the cleaning and conversion of low-grade coal needs to be developed. This special issue aims to report some of the efficient and facile beneficiation ...
