What is the composition of 'Copper matte'?

Matte is the phase where copper is extracted prior to the final reduction. The roasted ore is mixed with coke and silica (sand) S i O 2 and is introduced in to a blast furnace. The hot air is blasted and F e O is converted in to ferrous silicate (F e S i O 3 ). F e S i O 3 (slag) floats over the molten matte of copper.

Copper Smelting Metallurgist & Mineral Processing Engineer

Jan 13, 2021 The matte, about 45 to 55 percent copper and the remainder iron silicate slag, is formed in a very fast, almost instantaneous reaction; hence the name “flash smelting.”. The matte sinks through the lighter slag layer and flows down the. inclined crucible. Conversion to copper proceeds in a zone around position two.
