Abstract: Experiment of a pyrite cinder comprehensive recovery and utilization was done. The result indicated, combine process of water-washing pre-treatment—cyanide leaching—leaching residue magnetic separation was the best to adopt. Leaching rate of gold could reach to 41%,qualified iron concentrate of grade 60.90% and iron recovery rate 79.44% could obtained, indexes were ideal, comprehensive recovery and utilization of resources were realized.

Key words: Pyrite cinder, Cyanide leaching, Activation flotation
