Converter Matte

Converter Matte

 

an intermediate product (a nonferrous sulfide) in metallurgy, obtained during converter blowing of mattes. According to chemical composition, converter matte may be copper matte (Cu2S), nickel matte (Ni3S2), or cupronickel matte (Cu2S and Ni3S2). Copper matte is usually called white matte. Cupronickel matte is separated into copper sulfide and nickel sulfide concentrates by flotation before it is converted to metal.
