摘　　要：研究了某浮选金精矿的氰化浸出过程 ,考察了金精矿粒度、氰化钠浓度、氧化钙浓度、浸出时间及液固比等对该浮选金精矿氰化浸金率的影响。在最佳浸出条件下 ,其氰化浸金率可达到 97%以上。The cyanidation leaching process of certain gold concentrate of flotation was investigated. The effect of the particle size of gold concentrate, concentration of sodium cyanide, concentration of cacium oxide, leaching time and liquid solid ratio on the leaching rate of gold of this concentrate was stuided. Under the optimum leaching conditions, a leaching rate of gold could be over 97%.
