Selective flotation separation of ilmenite from

Sep 10, 2017· In the presence of DAA, the recovery of ilmenite increases rapidly with the increase of pH when pH < 6.0 and then reaches the peak value of 96% at a pH of 8.2, while the recovery of titanaugite remains around 50% in the investigated pH range. Thus, it is difficult to achieve selective separation of ilmenite from titanaugite using DAA alone.
