Abstract

In this study, the main aim was to recovery the gold from iron tailings, and comprehensive recovery of iron by using combined separating technology. Experimental studies were carried out on the iron tailings in Dahongshan samples, which contain 0.5g/t of gold and 16.8% of iron. Through the experiment, the first is pre-discarding tailings by centrifuge, and then the gold is recovered by cyanidation leaching with using of H2O2 to increase the rate of gold dissolution. The gold’s leaching rate can reach 97.60%. The qualified iron concentrate can be got from leaching slag and gravity tailings by magnetic separation. Iron tailings get a comprehensive utilization, which has a better effect.
