砷锰粘土金银矿中金、银的氰化试验研究

Experimental Study on Gold and Silver Cyanidation of Clay Kustelite Containing Arsenic,Manganese

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3～5h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。

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.
