copper smelting process

smelting Definition Facts BritannicaASARCO Smelting

The first metal to be smelted in the ancient Middle East was probably copper by bce followed by tin lead and silver To achieve the high temperatures required for smelting furnaces with forced air draft were developed for iron temperatures even higher were required Smelting thus represented a major technological achievementSmelting The Oxygen Flash Furnace At the Asarco copper smelter in Hayden Arizona the oxygen flash furnace is initially heated up with natural gas It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica bearing flux
