铁矿和某些多金属或者金矿床的选矿厂堆积着黄铁矿-砷黄铁矿的尾矿。利用硫化矿的尾矿是一项紧迫的任务,解决该任务以可解除环境污染,并成为廉价矿物原料的补充源泉。这充分说明,废弃一吨黄铁矿就等于从工业排给生活居区两吨硫酸。探讨利用硫化物尾矿的方法已经很久,但至今尚未找到令人满意的设备使用和符合经济 Iron ore and some polymetallic or gold ore mines piled pyrite - arsenopyrite tailings. Utilizing the tailings of sulphide ore is an urgent task to address the task of removing environmental pollution and becoming a source of additional sources of cheap mineral feedstock. This fully shows that discarding one ton of pyrite is equivalent to disposing of two tons of sulfuric acid from the industrial area. It has been a long time since we have explored ways to utilize sulfide tailings, but so far we have not found satisfactory equipment use and economy
