Feb 23, 2020 · Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall ...

· Uneven process air distribution in the concentrate burner has a negative impact on smelter performance, as was recently seen in the Huelva flash smelting furnace in Spain. The existing gas channel that fed process air to the burner was highly asymmetric and the air chamber was designed for a lower gas flow, and this was resulting in an uneven heat load on the reaction shaft walls. A shift ...

Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity ...

Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it causes the iron (Fe) in the copper concentrate to accumulate in the slag phase, while the copper (Cu), accumulates in the matte phase. Copper Concentrate
