【摘要】 由于Mn,Cu,Pb,Zn,As等元素干扰与包裹,砷锰粘土型金银矿中金银的氰化浸出效果较差。矿物与催化溶液反应3~5 h后,用炭浆法可以使金的浸出率从70%提高到91%~93%,银的浸出率从6%~10%提高到80%~90%,金银的氰化配合反应速度加快。试验对开发利用砷锰粘土金银矿资源具有很大的现实意义。更多还原

【Abstract】 Because of the disturbance and coating of Mn,Cu,Pb,Zn,As etc.,the leaching effect of gold and silver from the arsenic manganese clay-type kustelite is no good.The gold and sliver leaching rate could be improved from 70% to 91%～93% and 6%～10% to 80%～90% respectively by the carbon pulp process after 3~5 h reaction between clay-type kustelite with arsenic and manganese and the catalystsolutionand speed of the cyaniding coordination reaction was improved greatly.更多还原
