What is the composition of 'Copper matte'?

Copper Matte is the mixture of copper sulphide (C u 2 S) and some iron sulphide (F e S). 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 ).

What is Copper Matte? Chemistry Q&A

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).

Matte metallurgy Britannica

Matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and lead.Instead of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 40–45 percent copper along with iron and sulfur, which is then treated by converting in a Bessemer-type converter.

This matte, containing about 40% copper, can then be fed to a converter. Conversion of Matte into Blister Copper (impure copper) Air is blown through the molten matte which converts iron(II) sulfide to iron(II) oxide and sulfur dioxide. 2FeS + 3O 2 → 2FeO + 2SO 2(g) Iron(II) oxide, FeO, slag is

Extraction Of Copper Mining, Concentration, Smelting

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. \(Cu^{2}S + O^{2} → 2Cu + SO^{2}\) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2

12.3 Primary Copper Smelting

Copper matte remains in the furnace until tapped. Matte ranges from 35 to 65 percent copper, with 45 percent the most common. The copper content percentage is referred to as the matte grade. The 4 smelting furnace technologies used in the U. S. are reverberatory, electric, Noranda, and flash.

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or

Matte (metallurgy) Wikipedia

Matte is a term used in the field of pyrometallurgy given to the molten metal sulfide phases typically formed during smelting of copper, nickel, and other base metals.Typically, a matte is the phase in which the principal metal being extracted is recovered prior to a final reduction process (usually converting) to produce a crude metal.Mattes may also be used to collect impurities from a metal
