白银有色金属公司折腰山矿区,有部分块状含铜黄铁矿含锌较高(锌平均品位2％左右)。投产以来,一直将这类矿石做单一铜矿处理,不仅浪费锌矿资源,而且严重影响了铜精矿质量,造成冶炼过程中的困难。近几年来,为了回收这部分锌,我们曾应用氰化物、硫酸锌等十多种常用药剂和多种方案进行过试验,结果都不理想。遵照毛主席“人类总得不断地总结经验”的伟大教导,根据二氧化硫能抑制铅锌的原理,我
Silver non-ferrous metal company Yaoxian mountain mining area, some massive copper pyrite contains high zinc (zinc average grade of about 2%). Since put into production, this kind of ore has been treated as a single copper ore, not only wasting zinc resources, but also seriously affected the quality of copper concentrate, resulting in difficulties in the smelting process. In recent years, in order to recover this part of zinc, we have used cyanide, zinc sulfate and other 10 kinds of commonly used agents and a variety of programs were tested, the results are not satisfactory. In accordance with the great teaching of Chairman Mao, “mankind always has to sum up experience”, according to the principle that sulfur dioxide can restrain lead and zinc, I
