Outline
Taking a copper-silver polymetallic sulfide ore in Inner Mongolia as the research object, the process mineralogy analysis and flotation tests were carried out. The research results of ore properties show that except for a small amount of chalcopyrite, sphalerite and galena in the raw ore, copper and silver mainly exist in the form of silver tetrahedrite. The flotation tests show that, firstly, the copper-silver mixed flotation process is used to realize the separation of copper-silver minerals and sphalerite. Secondly, the mixed flotation concentrate is reground and floated to realize the separation of copper-silver and galena. Finally, the process flow of copper-silver mixed flotation-regrinding of mixed flotation concentrate-copper-silver flotation concentration is determined. The copper-silver concentrate with copper grade of 18.98%, copper recovery rate of 80.98%, silver grade of 10 521.88 g/t and silver recovery rate of 89.81% is obtained by closed-circuit test. By feeding the flotation tailings into the subsequent lead-zinc separation operation, the efficient comprehensive utilization of copper-silver mineral resources has been realized.
