柬埔寨某高硫金铜矿石选矿试验研究

Experimental study on the beneficiation of a gold-copper ore with high sulfide content in Cambodia

摘要: 柬埔寨某矿石属于高硫金铜矿石，根据矿石性质，确定采用铜浮选—金氰化浸出工艺流程回收矿石中的有价元素铜、金，在最佳试验条件下，获得了较好试验指标:铜精矿铜品位22.22 %、铜回收率72.23 %，金品位97.72 g/t、金回收率50.30 %;氰化浸渣金品位0.91 g/t，对原矿金浸出率41.00 %，金总回收率91.30 %。

Abstract: A ore in Cambodia belongs to gold-copper ore with high sulfide content.According to the ore property,the process flow of copper flotation-cyanidation gold leaching was adopted to recover the valuable elements of gold and copper from the ore.Under optimal test conditions,the indexes was satisfactory:the copper concentrate was obtained with copper grade 22.22 %,copper recovery rate 72.23 %,gold grade 97.72 g/t and gold recovery rate 50.30 %,the gold grade of cyanide residue was 0.91 g/t,the gold leaching rate of run-of-mill ore was 41.00 %,and the total gold recovery rate was 91.30 %.
