Study and application of the technology of pretreating cyanide gold-slime by low temperature roast followed by all-wet multimetal smelting

This technology,on the basis of the metallurgy of non ferrous metals,is an initiation of pretreating cyanide gold slime by low temperature roast followed by all wet multimetal smelting.It successfully causes precious metals separated from base metals and directly produces high quality of gold and silver bullions,of which the fineness is above 99.9%.By this technology,the comprehensive recovery tate of gold and silver is more than 99.95%.and the base metals as copper,lead etc are produced at the same time.Moreover,its capital and production costs are lesser.
