苏联矿物原料基地的总储量中,含贵金属的难选矿石的比重不断上升。过去不能利用的贫矿、细粒浸染矿石,含砷和含碳的矿石、小矿体、选矿厂和金选厂积存的尾矿,现在需要开采。因此,近几年极其重视改进含金银矿石的处理工艺,研究其发展的新方向。结果,获得了许多新的方法;其中一些已用于生产,其余的处于试验阶段。这里必须指出,贵金属矿石选矿的先进工艺和新工艺方法的出现,马.普拉克辛有很大的关系。
Among the total reserves of the Soviet Union’s mineral raw materials base, the proportion of refractory ore containing precious metals is on the rise. Lean ore, fine-grained ores, arsenic- and carbon-bearing ores, small ore bodies, ore dressing plants, and tailings stored at gold processing plants that were previously unavailable can now be mined. Therefore, in recent years, great attention has been paid to improving the processing technology of gold-bearing silver ore and studying new directions for its development. As a result, many new methods have been obtained; some of them have been used in production and the rest in the experimental phase. It must be pointed out here that the emergence of advanced processes and new technological processes for the processing of precious metal ores has a great bearing on Maraplaxin.
