Abstract: In order to determine the suitable technological conditions and reagent system,an experimental study on a submarine ore with 9.80% Cu and 44.24% S was conducted.The final closedcircuit test results showed that the copper concentrate contained 21.42% copper,the copper recovery rate was 8842%,the sulfur concentrate contained 5141% sulfur,0.718% copper,and the sulfur recovery rate was 5667%.The technological process and reagent system are reasonable,and the ore processing index is stable,which provides a research result with wide application for comprehensive recovery of copper and sulfur resources for this type of ore.

Key words: Submarine coppersulfur ore, Washability test, Separation of copper and sulfur
