摘要
本文从开发低品位矿和废矿、处理难选矿、强化由副产品中提金为目的的新工艺出发,论述了活性炭吸附法提金的重要性。介绍了二三十年来国外对活性炭于氰金溶液中吸附黄金的研究进展以及我国吸附黄金用活性炭的生产现状,并提出了几点看法。
Abstract Along with the industrial development , there emerges the new technology fordevelopment of low grade deposit and abandoned mines , for disposal of the ores difficultto be dressed, and for intensive extraction of gold from by-products. The method touse activated carbon to absorb gold receives increasing attantion. For this purpose , themain methods used are stack soaking method and carbon slurry method. Cyanide com-plex is largely absorbed by activated carbon, and deposited on its inner surface. Puregold is obtained by carbon baking , desorption, or elecrtolysis. The best activated car-bons used for such purpose are those made of fruit shells or stones. The chief material iscoconut shells. The substitute are peach stones , apricot stones , wallnut shells , oil teafruit shells , oil palm fruit shells and tatllowtree fruit shells. Besides these , there arecoal activated carbon and SCS type synthetic activated carbon in the former USSR wheremuch effort had been spent on their development. As to the industry in China to use ac-tivated carbon for gold absorption , the recommendations are made.
