【摘要】 介绍了处理秦皇岛某金矿矿石的研究结果。主要进行了混汞及预处理条件试验，提出了处理该矿的最佳工艺为混汞－预处理－氰化。在最佳工艺条件下，混汞可以回收45．1％的金，预处理后进行氰化金的浸出率达94．13％。更多还原

【Abstract】 The treating method of a refractory Qinhuangdao gold ores was studied in this paper. The optimum processing technique using amalgamation-pretreatment-cyanidation was proposed. It shows that 45. 1% of gold could be obtained by amalgamation and about 94. 13% leaching recovery could be achieved by cyanidation after pre-treatment.更多还原
