Pilot-Scale Demonstration of Ilmenite Processing

titanium. When re-grinding the ilmenite concentrate to 80% passing 37 microns, a leaching efficiency of 89% for iron and 88% for titanium was achieved. The ilmenite concentrate re-grind was estimated to consume 5.8 kWh per ton; therefore, total grinding energy consumption was estimated at 26.9 kWh per ton. Estimated leaching time was four hours.
