近几年来,丁基铵黑药在铅锌矿、铜矿选矿生产中,取得良好结果,深受有关厂矿的欢迎。但是,制造丁基铵黑药的原料之一——液氨供不应求,丁基铵黑药产量不能满足选矿生产的要求。为解决当前的这个矛盾,我们试制了丁基钠黑药并在有关矿山做了药剂选矿性能的试验,结果说明这种药剂性能良好。 In recent years, butyl ammonium black drugs in the lead-zinc ore, copper beneficiation production, and achieved good results, welcomed by the factories and mines. However, one of the raw materials for producing butyl ammonium black drug, liquid ammonia, is in short supply, the yield of butyl ammonium black drug can not meet the requirements of beneficiation production. In order to solve this current conflict, we trialled the production of sodium butyrate and tested the mineral dressing performance in the mines. The results show that the agent performs well.
