摘　　要：对焙烧料进行了水－酸浸出铜的试验研究，得到的铜浸出率在８０％以上。对浸出钢渣进行了氰化浸出金的研究，金的氰化浸出率达到了９７％。用０．１８ｍ２沸腾炉及１ｍ３浸出槽，进行了焙烧及浸出扩大试验，验证了小试结果，得出了可供工业设计的可靠参数与指标。Using solution of acid and water to leach copper--bearing gold concentrate,the leachingrate of copper reached more than 80%. Then, conduct fluidized roasting of the residue with 0. 18m2fluidized reactor. Again,using cyanide to leach the roasted products in the 1m3 leaching tanks,the goldleaching rate came to 97 %.Through this large--scale test, the reliable parameters and indices for industrial design were obtained.
