What is Copper Matte? - Chemistry Q&A
2022-2-6 · Copper matte is a mixture of copper sulfide (Cu 2 S) and some iron sulfide (FeS). Matte is a process in which copper is extracted before the final reduction. when a hot blast of air is blown through a molten matte placed in a silica lined converter, FeS of the matte oxidizes to FeO. This FeO combines with SiO 2 (silica) to produce FeSiO 3 ; (slag).

Copper Production: How Is Copper Made? - ThoughtCo
2019-9-26 · The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

Blister Copper - an overview | ScienceDirect Topics
Copper slag is produced during matte smelting and converting steps of pyrometallurgical production of copper from copper ores, when silica is added. It combines with the oxides to form silicates phases. The chemical composition of slag varies with the types of furnace or process of treatment (Cooper, 2005).
