It is shown that the residual collector molecules in the wastewater from the thickening of lead and zinc concentrates can benefit the formation of lead xanthanate onto the surface of galena, yet, some special chemical components in the wastewater from zinc tailings and effluent may induce some surface reactions on galena, and herewith the direct reuse of this water may bring disadvantageous influence on galena flotation.展开更多

In order to better promote the treatment effect of mineral processing wastewater and the development of recycling technology, this paper mainly introduces the source of mineral processing wastewater, water quality characteristics and harm, summarizes the natural purification, acid-base neutralization, coagulating sedimentation and other basic wastewater treatment technology, the source of mineral processing wastewater. The basic characteristics and hazards are briefly summarized, and the treatment of mineral processing wastewater is deeply studied. It is hoped to provide reference value for the effective development of the treatment of mineral processing wastewater in the future.展开更多
