Copper Refining Explained 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 copperIn these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath...
