Abstract

Abstract

Cu−Mo sulfide ores are often closely associated with each other and have similar floatability. Their flotation separation has always been the focus of research. Copper−molybdenum ore is generally separated by flotation method. The technology of Copper−molybdenum mixed flotation − copper−molybdenum separation is the most widely used process in the industry at present, after bulk flotation, usually the first pretreatment process, as far as possible to remove the flotation agents in copper−molybdenum bulk concentrate and desorption of residual agents from mineral surface, to provide conditions for copper−molybdenum separation. In this paper, the copper molybdenum separation pretreatment process is divided into three categories, one is desorption reagent removal method, the second is mechanical reagent removal method, and the third is the oxidation treatment of mineral surface. The first two are currently more commonly used pretreatment regent removal methods, but there are still complex processes, pollution and other characteristics, the oxidation treatment of mineral surface in addition to the purpose of reagent removal, but also to achieve the surface oxidation of copper minerals, increase floatability difference between copper and molybdenum minerals. Through the research and technical summary of flotation separation pretreatment technology of copper−molybdenum mixed concentrate, it is of great significance to improve the separation effect of copper−molybdenum mixed concentrate.
