Abstract. This paper summarizes several flotation methods of copper and molybdenum ore, introduces the research progress of flotation collector and inhibitor of copper and molybdenum ore, and points out that the research and development of new efficient collector and copper and molybdenum beneficiation inhibitor is the key to comprehensive recovery of copper molybdenum ore resources.
Abstract. According to the mineralogy of the polymetallic ore,the process of preferential flotation of copper was adopted, and the separation of lead, zinc and sulfur were carried out and implemented.Four products, including copper concentrate assaying 22.67% Cu at a recovery of 91.77%, lead concentrate assaying 18.10% Pb at a recovery of 12.74%, zinc concentrate assaying 47.13% Zn at a recovery of 85.89%, sulfur concentrate assaying 37.42% S and a recovery of 31.40%, were obtained by the preferential flotation in the order of copper, lead, zinc and sulfur.The flowsheet recommanded provides the reference for the future commercial operation of the processing plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
