摘要： Percolation leaching of gold or silver ores, tailings or wastes is accomplished by a process comprising initial agglomeration of fines in the feed by means of a binding agent and cyanide solution, followed by aging and, subsequently, leaching to recover gold or silver values.

摘要： An electrolytic process for the desorption of precious metals such as goldnd silver. The precious metal complexes are loaded on activated carbon particles that are packed into a hollow, cylindrical graphite container and the container is connected as the anode of an electrolytic cell. The electrolyte is a suitable alkaline solution and the cathode can be graphite, antimony or copper. Upon the application of an electric current, the precious metal complexes are desorbed and reduced to precious metals on the cathode.
摘要翻译： 用于解吸贵金属如金和银的电解方法。 贵金属配合物装载在填充到中空的圆柱形石墨容器中的活性炭颗粒上，并且容器作为电解池的阳极连接。 电解液是合适的碱性溶液，阴极可以是石墨，锑或铜。 在施加电流时，贵金属络合物被解吸并还原成阴极上的贵金属。
