目前,处理一些含金矿石所采用的工艺流程,一般都是先对原矿进行浮选,并对浮选尾矿进行氰化,浮选时矿石的大部分金转入浮选精矿,后者再运到炼铜厂,用火法进行处理.由于运输这些精矿需要付出大量运费,并造成金的损失.因此,近年来对于研究就地处理浮选精矿的工艺流程给予极大的重视.例如先对浮选精矿进行氰化,然后从清液中提取金,就是这样的一种流程.照我们看来,采用流通型多孔体阴极设备的电解法,乃是最经济的一种提金及伴生银的方法.
At present, the process used to process some gold-bearing ores typically involves first flotation of the ore and cyanation of the flotation tailings, with most of the gold in the flotation being transferred to flotation concentrates, the latter And then shipped to the copper smelter, the fire method for processing.As the transport of these concentrates need to pay a lot of freight, and cause the loss of gold.Therefore, in recent years for the study of flotation concentrate in-situ process gives great attention For example, cyanidation of flotation concentrate followed by extraction of gold from the supernatant is one such process, which, in our opinion, is the most economical method of electrolysis using a flow-through porous cathode device Gold and associated silver method.
