摘　　要：以金精矿氰化尾矿为原料的硫酸厂每年产生大量的含金硫酸烧渣,由于金含量低、回收率低、处理成本高,目前仅以很低的价格卖给水泥厂做熟料,大量的黄金白白流失。A lot of gold - bearing sulfuric - acid slag produced from sulfuric - acid plants using cyanidation tails of gold concentrate as raw materials are soled to cement plants now because It＇s not only has low gold content and recovery, but also higher production costs. Then lot of gold is lost. The new process can recovery gold economically from the slag by chlorine leaching and extracting gold from leach liquor with active carbon, the new process will be industrialized with more simple technology and lower invest and cost, no environment pollution also.

关 键 词：硫酸烧渣 氯化浸出 黄提取工艺
