The final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels. This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining.

Making metals - sda-uk.org

Finally, before the metal can be used, it often has to undergo further processing. For example, 98% pure ‘blister copper’, created by smelting and reduction, then has to be ‘electrorefined’ to produce copper of 99.99% purity. Making metals in this way is not very sustainable. Mining and processing use up enormous amounts of energy.
