copper matte_copper matte

copper matte converting system is a complicated process which has the characteristics of multivariable, nonlinearity, strong coupling, large inertia, time varying and uncertainty and very difficult to carry out real - time on - line control . the purpose of the optimization, decision - making and control of copper matte converting process is …


Copper Production Processes :: Total Materia Article

Several different processes can be used for copper production. The old traditional process is based on roasting, smelting in reverbatory furnaces or electric furnaces for more complex ores, producing matte and converting for production of blister copper which is …


Copper Smelting

Seventy-five percent sulfur dioxide is regularly produced by flash smelting copper concentrate, using pure oxygen, at the Sudbury, Ontario, smelter of the International Nickel Company. In this plant (the only flash smelting process in the Western Hemisphere) copper concentrate is smelted to about 45-percent matte.


Production of Matte, White Metal, and Blister Copper by …

Outokumpu Oy has intensively studied the production of high-grade copper matte in a flash smelting furnace since the 1950s. Blister copper was first produced in the pilot furnace of the Metallurgical Research Centre at Pori in 1969 and the first commercial plant for direct blister production was commenced in 1978 in Poland.


What is Copper Matte?

Copper matte is made up of copper sulfide (80-95 percent) and Fe – Co alloys (five to seventeen percent). Metallic copper, silver, Pb – Ag alloys, and arsenide can all be found in addition to Fe – Co. Finally, the copper matte is a mixture of copper sulfide and a small amount of iron sulfide recovered during the matte process.

Production

The smelting products are copper matte, waste slag and process gases for the production of sulfuric acid. b) Copper matte is processed in the converter-anode section (CAS) to produce …


COPPER Copper production

Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3.

Copper Production: How Is Copper Made?

Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80% of global copper production is extracted from sulfide sources.

Copper Production

The copper ores are crushed, ground, and undergo concentration by froth flotation, matte smelting, and converting to blister copper. The blister copper must undergo additional steps of fire refining and electrolytic refining before the purity of copper increases to 99.99% suitable for most applications. 2.1.1. Principles of Copper Production



Copper Matte

Matte, copper is defined as : Substance resulting from metallurgic processing of primary and secondary sources. The matte is obtained from copper ore/concentrate and recycled materials. It is composed primarily of copper and copper, iron and lead sulphides with minor sulphides of …


Global Copper Matte Market Report 2022

Copper Matte Production In value terms, copper matte production declined to $X in 2021 estimated in export price. The total output value increased at an average annual rate of +X% from 2012 to 2021; the trend pattern remained relatively stable, with somewhat noticeable fluctuations being recorded in certain years.

The operational challenges and environmental concern of batch-wise Peirce-Smith Converting vessel have induced more than 50 years ago attempts to continuous converting process which have...




copper processing

These are heated by combusted fuel or electric current to a temperature of 1,230–1,300 °C (2,250–2,370 °F), producing an artificial copper-iron sulfide that settles in a molten pool at the bottom of the furnace. The sulfide material, …


Introduction of Matte Droplets in Copper Smelting Slag

Smelting is an important process in copper production to produce matte and slag. The slag, containing about 1–12% Cu, can be further processed to recover the copper contaminated, but recycle of the slag concentrate reduces overall productivity and efficiency of the operation. The best solution is to minimize the copper loss to the slag.
