Jhamarkotra phosphate ore processing plant

Low grade phosphate ore of Jhamarkotra that analyses 16.5% P2O5 is upgraded to 34% P2O5 by a two stage flotation process after size reducing the ore to 90% passing through 200mesh using conventional equipment such as jaw and cone crushers followed by ball mills. Reengineering the flotation circuit reduced the power consumption from 55 kWh per metric ton of ore treated to 50 kWh. Incorporation of roller press (HPGR) in the grinding circuit resulted into further reduction of power consumption to 32 kWh per metric ton of ore treated.
