Abstract
The invention discloses a beneficiation method for treating copper smelting slag, which aims to solve the problem that the existing flotation can not obtain higher recovery rate under the condition of ensuring the concentrate grade. The method adopts the sectional flotation of the copper minerals contained in the copper slag, namely, part of the copper minerals which are easy to float are quickly floated, and then the part of the copper minerals which are difficult to float are floated. Grinding copper smelting slag, namely raw ore, to a certain fineness, collecting copper minerals by adding a copper smelting slag collecting foaming agent, wherein the combined collecting foaming agent is as follows: sodium n-butyl xanthate, ammonium dibutyldithiophosphate, diethylamino dithioformic acid cyanoethyl ester and terpineol oil. The beneficiation method has simple process, is easy to manage and operate on site, and can obtain higher economic and technical indexes by adopting the process. The used reagent is environment-friendly, and the grade and the recovery rate of the finally obtained copper concentrate are high.
Description
