Abstract:

The sulfide concentrate bearing silver was flotation from tin separation tailings in a Bolivia mine which contained Au 1.03×10-6,Ag 178.7×10-6,Cu 0.53%.Most of the gold and silver were covered by sulfide.In order to comprehensive recover the valuable elements in sulfur concentrate,the process of“additive roasting-acid making by flue gas-recovery of copper by acid leaching-recovery of gold and silver by cyanidation-tailings for sale”is adopted.Test results show that when additive is used for roasting,the recovery rate of gold,silver and copper have been greatly improved,the final correspondingly lenching rate of these valuable metals are 80.07%,90.32% and 89.55% respectively.The preliminary economic evaluation showed that the total value of production is 1 471.51 yuan per ton,excluding raw material the total cost of production is 1 228.13 yuan per ton.This process realizes the comprehensive utilization of secondary resources and provides a new way of energy saving and emission reduction for enterprise.

Key words:  sulfide concentrate bearing silver, comprehensive utilization of resources, silver recovery ratio, cyaniding, roasting, economic evaluation
