Metallurgy Matte Smelting, Refining, Alloying Britannica
Metallurgy Matte Smelting, Refining, Alloying: The primary purpose of matte smelting is to melt and recombine the charge into a homogeneous matte of metallic copper, nickel, cobalt, and iron sulfides and to give an iron and silicon oxide slag. It is done in many types of furnace on both roasted or unroasted sulfide feed material. The reverberatory furnace is Noranda furnace is formerly called Noranda reactor, it is horizontal cylindrical bath smelting furnace. Copper concentrate ore, copper containing material, flux and fuel are proportionally mixed and loaded into furnace by thrower. Oxygen rich air are blasted into furnace from tuyere, which makes the molten bath in a stirring state, raw Noranda Furnace Refractory RS Kiln Refractory Bricks
