2012-4-30  Using reduction roasting–water leaching–magnetic separation method, the recovery of iron from cyanide tailings was optimized. The recovery of iron was highly depended on the water-leaching process after reduction roasting. The results suggest that the method can be effectively used for iron recovery, and the grade of magnetic concentrate and recovery rate can reach 59.11% and 75.12%,
