COPPER Copper production - Repository

In the first flotation stage, as much copper as possible is recovered in a rougher concentrate so that as little as possible goes to the tailings. To increase the copper recovery rate, often these tailings are leached with sulfuric acid. After regrinding, the rough concentrate is -2 of 11-cleaned in several flotation steps. After sedimentation in thickeners and filtration in automatic filter ...
