The invention relates to a
beneficiation method for efficiently recovering
copper from
copper smelting slags. The
beneficiation method is particularly suitable for further
copper recovering from the copper
smelting slags generated through carrying out copper
pyrometallurgy processing on copper concentrate. In the invention, rough
grinding and grading are adopted for obtaining selected raw materials reselected by a spiral chute, reselected copper concentrate is obtained through reselection operation, and then preferential flotation copper concentrate, flotation copper concentrate and final
tailings are obtained through fine
grinding, preferential flotation, one-time roughing, two-time
scavenging and three-time concentration. In the preferential flotation, roughing and
scavenging processes,a combined collecting agent is used in cooperation, middlings successively return to a last operation section, and finally qualified copper concentrate is obtained. The method is advanced in process,high in treatment capacity, good in separation effect, and stable in operation, copper in the copper
smelting slags can be effectively recycled, a Cu grade of the copper concentrate is greater than orequal to 23.22%, and a Cu recycling rate of the copper concentrate is greater than or equal to 95.13%. And valuable
resource recovery efficiency of the smelting slags is improved, and
economic benefits are brought to enterprises.
