The author studied the process of copper removal from underspoil water at Blyavinskoe and Safyanovskoe copper ore deposits by cementation by iron. The influence of pH, consumption of cementation agent impurity ions Fe 3+ , Al 3+ and Ca 2+ , as well as timing on the cementation performance was analyzed. The mechanism of the process was determined, and by-reactions resulting in over-consumption of cementation agent were revealed. The studies of the material constitution of cemented copper showed that the concentrate quality worsened because of the joint settling of basic aluminum and calcium sulfates. The obtained results make it possible to draw the conclusion on applicability of cementation for removal of copper from underspoil water.

用胶结法去除矿井底污水中的铜

作者研究了通过铁胶结从 Blyavinskoe 和 Safyanovskoe 铜矿床的未污染水中去除铜的过程。分析了pH值、固井剂杂质离子Fe 3+ 、Al 3+ 和Ca 2+ 的消耗量以及时间对固井性能的影响。确定了该过程的机理，并揭示了导致胶结剂过度消耗的副反应。对胶结铜物质组成的研究表明，由于碱式硫酸铝和碱式硫酸钙的共同沉降，精矿质量变差。所获得的结果可以得出关于胶结用于从未污染水中去除铜的适用性的结论。
