The Horne smelter has the capacity to process 840,000 tonnes per annum of copper and precious metal bearing materials. One of the notable features of the Horne smelter is its ability to process a wide-range of feeds, including copper and precious metal bearing electronic equipment.
Flash smelting is a closed process and, consequently, off-gas emissions can be efficiently controlled. Flash converting had its first application in the expansion and modernization of Kennecott's copper smelter near Salt Lake City, Utah, which was implemented during 1992-95.
The smelter uses state-of-the-art technology such as this X-ray fluorescence spectrometer to determine the mineral and chemical content of the various process material streams. Repeatedly analyzing samples from all the various production material streams is a constant and ongoing endeavor necessary to control the smelting process.

Mar 06, 2019· 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. This is accomplished through a series of several processing steps.
Copper Smelting Key Concepts. Rocks are mixtures of minerals. ... Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO.
This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining.

The Smelting Industry: Global Importance And Risks Smelting is a metallurgical process used to extract base metals from the ores they are contained within. Smelting iron at a steel mill in the Ukraine.
Early Smelting Practice. Virtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken. Originally it was probably smelted by the Sumerians in shallow pits using charcoal as the fuel.
The Copper Flash CC Smelting Process Abstract: Copper flash smelting is a relatively new process which has been in operation since the 70's and is a pyrometallurgical process used in conjunction with copper sulphide concentrates.
Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.
The reverberatory furnace dominated copper matte smelting for much of the 1900s, because it was an excellent process for smelting fine concentrate from flotation. It is a fossil fuel fired hearth furnace for smelting concentrate and producing copper matte. The reverbs began to decline in the
Nov 22, 2015· The smelting process of copper smelting furnace is beneficiation, its purpose is to concentrate all the gangue content in slag, and useful metal in blister.
Copper from the smelter is melted and cast as anodes, the solution from the solvent extraction process moves to a plating operation. 7. Sulfide Ore Refining. The final step in processing sulfide ore copper from the smelter is to make high purity copper cathodes. 8. Copper Products & Many Uses
Copper Smelting Furnace View Larger Image The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea.

Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver.
The Mitsubishi process has been selected as a smelting unit. This process is only one truly continuous process established in a commercial scale all over the world, which has a superior technology for copper smelting and converting.
