Abstract: There are some valuable metals such as copper,lead and silver in the cyanide leach residue of a gold mine in Henan province.A simple flowsheet by using a mixed collector LD is adopted in this experiment to research comprehensive utilization of the cyanide leach residue containing copper,lead and silver.It can gain a copper concentrate which grade is 21.82% Cu and total recovery is 96.58%.A lead concentrate which grade is 58.20% Pb and total recovery is 74.83% has been obtained.This technology has been popularized and good economic and societal gain has been obtained.
