实验室中进行了从尾矿中除去含硫物料、主要是黄铁矿的浮选和重选试验．这种物料是产生酸的根源．浮选中组合使用黄药类捕收剂、调整剂和起泡剂．黄铁矿的回收率取决于被处理的尾矿，平均为42～97％．给矿中含流量12.8％～0.37％,处理后减到8.68～0.01％．浮选试验用来评价尾矿中黄铁矿含量与酸性岩排出物（ARD）的关系．标准ARD预测试验用来评价处理的可行性．在某些情况下．只要除去50～55％的黄铁矿，就可使尾矿由酸性转变成非酸性．用实验室摇床试验，来评价含硫尾矿重选分离的可行性，黄铁矿回收率38～86％．给矿中含硫12.8－0.37％，处理后含硫6.0～0.14％，对尾矿进行的的ARD预测试验表明，重选前后，大多数含硫样品从“可能”变成了“不一定”产酸。本文报道的数据和分析表明：采用常规浮选和重选技术除去含硫尾矿中的金属硫化物，可以控制ARD的产生．
Laboratory carried out from the tailings to remove sulfur-containing materials, mainly pyrite flotation and re-election test. This material is the source of the acid. Flotation combined use of xanthate collectors, regulators and foaming agents. The recovery of pyrite depends on the tailings being treated, averaging 42-97%. To the mine with flow of 12.8% ~ 0.37%, reduced to 8.68 ~ 0.01% after treatment. Flotation tests were used to assess the relationship between pyrite content in tailings and acid rock discharge (ARD). The standard ARD prediction test is used to evaluate the feasibility of the treatment. In some cases. As long as the removal of 50 to 55% pyrite, you can make the tailings from acidic to non-acidic. Using laboratory shaker test, to evaluate the feasibility of sulfur tailings re-separation, pyrite recovery of 38 ~ 86%. The ARD predictions of tailings from 12.8-0.37% sulfur in the mine to 6.0- 0.14% sulfur in the treatment showed that most of the sulfur-containing samples changed from “possible” to “not necessarily” before and after re-election, Acid production. The data and analysis reported in this paper show that the production of ARD can be controlled using conventional flotation and reselection techniques to remove metal sulfides in sulfur-bearing tailings.
