摘要
鄂西某高磷鲕状赤铁矿经过重选—磁选—反浮选—蚀胶法浸出的选矿过程,会产生大量废水,其中反浮选过程产生碱性废水,蚀胶法浸出过程产生酸性废水。对所产生的废水进行了中和处理回收实验研究。研究结果表明,废水经处理后可达到国家排放标准,并可回收其中的酸。
The high-phosphorus oolitic hematite in the west of Hubei after re-election-magnetic sepa- ration-reverse flotation-iron leaching beneficiation process will produce large amounts of waste water, reverse flotation process produce large amounts of alkaline waste water, iron leaching process will produce large a- mounts of acidic waste water. This article made an experimental study on the produced waste water, inclu- ding neutralizing treatment and recovery. The research results show that the waste water can be treated and meet the national emission standards, reached harmless to the environment.
