In pyrometallurgy, copper concentrate is dried before being heated in a furnace. Chemical reactions that occur during the heating process cause the concentrate to segregate into two layers of material: a matte layer and a slag layer. The matte layer, on the bottom, contains the copper, while the slag layer, on the top, contains the impurities .

The resulting mixture, called a copper concentrate, contains about 25-35% copper along with various sulfides of copper and iron, plus smaller concentrations of gold, silver, and other materials. The remaining materials in the tank are called the gangue or tailings. They are pumped into settling ponds and allowed to dry. The process of .
Smelting. 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. The silica flux binds with the iron and other .
Which copper concentrate treatment process is preferred, Hydro-metallurgical or Pyro-metallurgical ?I understand it depends on the copper concentrate grade.
