Abstract:Deep-sea polymetallic sulfide mineral resources are rich in copper, zinc, cobalt, gold, silver and other strategic metals, which is one of the potential resources for future development and utilization of human beings. In this paper, mineral processing and metallurgical processes of a deep sea polymetallic sulphide were studied, and useful elements were separated and extracted. The “pre-leach-beneficiation-smelting extraction” suitable for high sulfur fine-grain copper-zinc polymetallic sulfide was determined, and the preliminary recovery of valuable metals in the samples was realized, and the comprehensive recovery rate of copper and zinc reached 96.65% and 90.31%, respectively. Combining the characteristics of the deep-sea polymetallic sulfide, an efficient and clean agent BK915 was developed, which solved the problem of separation of high sulfur fine-grained copper-zinc polymetallic sulfides and provided a technical reference for the subsequent development of deep sea polymetallic sulfides.
