我地区民采黄金矿山的氰化生产,都是采用锌丝置换法回收责液中的金。贵液从氰化浸出池排出后直接进入置换槽。由于贵液在排放过程中带有相当数量的悬浮物,而这些悬浮物会污染锌丝的表面,降低了金的置换率及消耗溶液中的氰化物。据对容县选厂氰化生产过程的测定,贵液中悬浮物的含量达58ppm,金的置换率只有57.45％。在置换槽的第一格中加放了约2公斤粒度为-3+1毫米的白云石进行过滤之后(见附图),锌丝
In our region, mining of gold mine cyanide production, are using zinc wire replacement method to recover the liquid gold. Excretion of the liquid from the cyanide leaching tank directly into the replacement tank. Because your liquor carries a significant amount of suspended matter during its discharge, these suspensions can contaminate the surface of the zinc wire, reducing the gold exchange rate and depleting the cyanide in solution. According to the determination of yung county plant cyanide production process, your liquid suspended solids content of 58ppm, gold replacement rate of only 57.45%. About 2 kg of dolomite with a particle size of -3 + 1 mm was placed in the first compartment of the displacement tank for filtration (see the attached drawings), and the zinc wire
