Sequential flotation of sulfide ores Anschutz Mining

Sequential Flotation Of Sulfide Ores Anschutz Mining

A sequential flotation process for the recovery of high-grade concentrates of copper, lead and cobalt-nickel from sulfide ores is provided. A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper.

Grinding Mineral Processing

Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.
