Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air. The product from

Lime use and functionality in sulphide mineral

The other common process to treat these ores is sequential flotation stages, each of which is optimized for the selective recovery of one mineral over the others. The order is generally Cu, followed by Pb and Zn sulphides, respectively. This is because there is a window of pH values at which copper (pH 5–6), lead (pH 7–7.5) and zinc (pH > 10) can be floated from each other
