Abstract:

Copper is an important key metal raw material.It is of great significance to comprehensively recover and utilize copper ores containing precious metals such as gold and silver.The process mineralogy and beneficiation test of a copper sulfide ore containing gold and silver in Henan Province have been carried out.The results show that the main useful element copper content is 0.82%,the associated beneficial groups are sulfur,gold and silver,the main useful metal minerals are chalcopyrite,chalcocite,pyrite,gangue minerals are mainly quartz.The combined collector of butyl xanthoxanthate and butyl ammonium black is used in mixed flotation,the total amount of agent is 120 g/t,and the process flow of one coarse,two fine and three sweeps is adopted.The new collector TB1021 is used in copper sulfur separation flotation,and the process flow of one coarse,three fine and three sweeps is adopted.Finally,a copper concentrate with a copper grade of 15.21% and a copper recovery of 80.13%,a gold grade of 3.02 g/t,a gold recovery of 66.51%,a silver grade of 160.43 g/t and a silver recovery of 41.82%,and a sulfur concentrate with a sulfur grade of 49.13% and a recovery of 54.34% were obtained.

Key words: copper sulfide, mixed flotation, copper and sulfur separation, flotation reagent, beneficiation test, comprehensive recovery
