Toyo Smelter & Refinery | About Us

Mined ore which has a copper grade of less than 1% is turned into copper concentrate with a purity of about 30% at mine site and transported to the Toyo Smelter & Refinery. In addition to copper, copper concentrates contain about 30% each of iron and sulfur, and trace amounts of gold, silver and other precious metals, all of which are recovered.

Copper Refining: Explained Step-by-Step

In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.In these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.
