红透山铜矿尾矿含硫6～8%,粒度-0.15毫米。开路和闭路试验表明,采用简单的药剂制度和流程回收黄铁矿,可以获得满意的指标。硫在尾矿各粒级的分布如表1。在开路试验的基础进行了闭路试验。闭路试验共进行三次,都采用尾矿水调浆。试验流程是粗选,一次精选、一次扫选,和复选一次。精选的精 Hongtoushan copper mine tailings sulfur 6 ~ 8%, particle size -0.15 mm. Open and closed-circuit tests have shown that satisfactory results can be obtained using a simple pharmaceutical system and process recovery of pyrite. The distribution of sulfur in each grade of tailings is shown in Table 1. Closed circuit test was carried out on the basis of open circuit test. A total of three closed-circuit tests have been tailings slurrying. The test process is rough, a selection, a sweep, and check again. Featured fine
