COPPER Copper production TU Delft

Figure 4 gives an overview of a typical beneficiation process at a concentrator. 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.
