Abstract

The invention discloses a method for floating and separating copper and nickel from high nickel matte and relates to the method for sorting copper concentrate and nickel concentrate from high nickel matte by using a flotation column. The method is characterized in that the flotation column is adopted to perform a flotation process. According to the method for floating and separating the copper and the nickel from the high nickel matte, the flotation column is applied to all the production flow of rough flotation, scavenging flotation and precise flotation, so that the automation degree is high; a proper technical condition is selected, so that the technical flow is short and the operation is convenient to perform; the equipment is little; the operation cost is low; and the technology is reliable and convenient to perform.

Description

technical field [0001] The invention relates to a method for separating copper and nickel by flotation of high-nickel matte, which relates to a method for separating copper concentrate and nickel concentrate by adopting a flotation column to high-nickel matte. Background technique [0002] At present, the separation of high-nickel matte has always been carried out by flotation machines. In the large-scale separation process of high-nickel matte, it is necessary to equip a large number of flotation machines or to enlarge the flotation machines, thus causing the flotation machines to match each other. components with high performance. [0003] The use of flotation columns to carry out flotation of minerals has been widely used in recent years. Currently, there are four types of flotation columns, including packed media flotation columns, short-body jet flotation columns similar to the Australian Jameson, cyclonic microbubble flotation columns, and CCF countercurrent contact g...
