中文摘要: 采用沸腾焙烧—酸浸—氰化工艺处理高铜金精矿。工业实践表明,对于铜品位7%~10%的金精粉,全流程铜的回收率达到97%,酸浸渣含铜低于0.3%,氰化金浸出率96.84%,银浸出率75.45%,烟气SO2总转化率平均98.74%,处理后的烟气SO2浓度0.061%。
Abstract:High-grade copper-bearing gold concentrate was treated by processes of fluidized sulfating roasting, acid leaching, and cyaniding leaching. The industrial practice shows that copper total recovery rate is 97%, copper in acid leaching slag is below 0.3%, gold and silver cyaniding leaching rate is 96.84% and 75.45%, the average total conversion rate of SO2 is 98.74%, and SO2 concentration in waste gas is 0.061% when the gold concentrate bearing 7%~10% copper is treated by the above processes.
