Matte (metallurgy)
Matte is a term used in the field of pyrometallurgy given to the molten metal sulfide phases typically formed during smelting of copper, nickel, and other base metals Typically, a matte is the phase in which the principal metal being extracted is recovered prior to a final reduction process (usually converting ) to produce blister copper [1]Copper processing Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of eitherCopper processing Roasting, Smelting, Converting | Britannica
