本文研究了在酸性介质中用硫脲从矿石中提取金和银的方法.还研究了不同数量的氧化剂对浸出的影响.转盘试验发现,当含浸取液硫脲1.0%、硫酸0.5%、高铁离子0.1%时,金和银的溶解速度比在含氰化钠0.5%,氧化钙0.05%的浸取液中快10倍以上.从实际的硫脲溶液提取金和银的初步研究,也是令人鼓舞的. In this paper, we studied the method of extracting gold and silver from ores using acidic thiourea, and studied the effects of different amounts of oxidants on the leaching.It was found from the turntable experiments that when thiourea was impregnated with 1.0% sulfuric acid, 0.5% sulfuric acid, At 0.1% ION, the dissolution rate of gold and silver is more than 10 times faster than that of a solution containing 0.5% sodium cyanide and 0.05% calcium oxide. A preliminary study of the extraction of gold and silver from an actual thiourea solution also led to People encouraged.
