The iron will react with the copper sulfate, producing iron sulfate and elemental copper.
The first step is extracting copper from its ore, including the sulphate, to remove waste constituents like limestone and silica so that the copper and other minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step is to smelt (blast furnace with coal) or leach (reacting with an acid then using electrolysis) the product which also removes a large amount of impurity elements like iron and for sulphide ores, sulfur. The final step, refining, removes the last traces of the impurity elements and produces a copper product of 99.99 percent purity.
