摘要
溶浸采矿是从贫矿、残矿、废石堆、尾矿中提取金的一种行之有效的方法。本文以试验研究为例,介绍该法的制粒—氰化预处理—堆浸提金新工艺。试验研究以含泥及粉矿产率高的低品位金矿物为对象。试验结果表明,制粒—氰化预处理—堆浸可改善含粘土质矿的渗透性、提高金的浸出率、加强浸出速度、缩短浸出周期、降低成本及改善环境条件。
Solution mining is a available method to extract gold from lean ore, relic, waste dumps and tailings. Based on the experiment research for low grade gold minerals containing high proportion of clay and powder, a new gold extraction process, i.e. granulation-cyaniding pre-treatment-heap leaching is described. The results show that this new process can enhance the gold leaching rate from the clay-containing ore, increase the leaching speed, shorten operational cycle, cut production costs and improve environment conditions.
