一、前言为了解决丁基黄药供不应求的问题,于82年3月至4月中旬对粗丁基黄药进行了小型选硫试验。试验结果表明,粗丁基黄药可以代替丁基黄药,在此基础上,于82年5月至6月末,在三十亩地选矿厂选硫车间进行了粗丁基黄药代替丁基黄药的工业性试验。试验共进行79个班,处理矿量104305.53吨,硫精矿品位42.70%,回收率比丁基黄药高4%以上,用量相差不大,该选矿厂选硫采用此药剂,予计每年可增加收益12万元。 I. Preface In order to solve the problem of butyl xanthate in short supply, a small sulfur-selective test was conducted on crude butyl xanthate from March to mid-April of this year. The results showed that crude butyl xanthate could replace butyl xanthate. On the basis of this, crude butyl xanthate was substituted for butyl in the sulfur selective workshop of 30 mu of the ore dressing plant from May to the end of June, Xanthate industrial test. The experiment carried out a total of 79 classes, dealing with 104,305.53 tons of ore, sulfur concentrate grade 42.70%, the recovery rate of butyl xanthate more than 4%, the amount of difference is not large, Increase revenue 120,000 yuan.
