用酸性硫脲溶液浸出金和银的速度要比通常的氰化法高得多.用硫脲作为一种浸出介质从矿石中提取金和银,主要是由于它有与金属形成络合物的能力.金属离子和硫脲分子之间形成的络合物被认为是由很强的协同配位键所形成的结果.用酸性流脲溶液浸出金和银的化学性质和在水冶中应用这个反应的可能性首次作了总结和讨论.对化学和电化学的试验结果也作了进一步地讨论.用硫脲作金和银的水冶药剂尚处于初期研究阶段,这种工艺的可行性还在探索中.
Leaching gold and silver with an acidic thiourea solution is much faster than the usual cyanidation method.Using thiourea as a leaching medium to extract gold and silver from ore is mainly due to its complexation with metals The ability to form complexes between metal ions and thiourea molecules is believed to be the result of strong coordination coordination bonds.The chemistry of gold and silver is leached with an acidic solution of urea and this The possibility of reaction is summarized and discussed for the first time.Chemistry and electrochemical test results are also discussed further.With thiourea as gold and silver water metallurgy agent is still in the early stages of research, the feasibility of this process also In exploration.
