Beneficiation

Looking to the scarce rock phosphate resources in India, RSMML has put continuous effort for utilization of its low grade ore resources, which are abundant at Jhamarkotra but require beneficiation before its utilization by fertiliser industries as raw material. Intensive research was carried out for ten years and a breakthrough in processing technology was achieved when this LGO was enriched to produce a very high-grade concentrate (+34%P2O5), rated as equal to or better than any naturally occurring ore. From reserves conservation point of view RSMML has put up a beneficiation plant for processing of 9 Lacs MT of low-grade ore per annum.
