The Bingham Canyon Mine is one of the world''s largest open pit copper mines. Processing facilities include a concentrator, a 175megawatt (MW) coalfired power plant, a copper smelter, and a copper refinery. The operation produces 300,000 tons of refined copper per year plus significant quantities of gold, silver, and molybdenum.
The customer in this case can be a smelter, who onsells blister copper ingots to a refiner, or a smelterrefiner which is vertically integrated. One prevalent form of copper concentrate contains gold and silver, like the one produced by Bougainville Copper Limited from the Panguna mine from the early 1970s to the late 1980s.
In this paper methods under development in COCOP for optimisation of a copper smelter including plantwide control and unit process advisory tools, are introduced and discussed. The main focus of the paper is in describing the development work relating to the optimisation of the PeirceSmith unit process.
Various slag systems have been considered for directtoblister smelting. They have been evaluated computationally, using the MPE thermodynamic modelling package, and practically, at pilot scale. The limesilicairon oxide slag was found to have the lowest slag make, lower dissolved copper and hence lowest copper losses.
Corporation (YCC), in November 2006, and the smelter began producing copper at the end of 2008 • The IsaSmeltsmelter was initially designed to produce 150 kt/a of blister copper, but has since been expanded to reach 250 kt/a of blister copper (which represents a smelting capacity of 750 kt/a of feed)
A variation of the DirecttoBlister Flash Smelting process is the KennecottOutokumpu Flash Converting Process eliminating the Peirce Smith converters and molten material transportation in the converter aisle. Outokumpu developed this process in collaboration with Kennecott and the first plant was built by Kennecott Utah Copper in USA in 1995. ...

The process routes of primary copper production [10]. The primary smelter and refinery plant uses concentrate as a raw material, produces copper cathodes, sulphuric acid, and precious metals, and discards slag and offgases. Up to the production of blister copper in the converter, the main target is to remove iron and sulfur. After blister copper
There was a waterjacket blast furnace, and a later concentrating plant and converter added to produce blister copper. The smelter closed in 1918 due to the fall in the price of copper. The copper smelters and furnace types operating in Australia in 1917 and .
Copper scrap is often classified according to its source: (1) direct or "home scrap", which is the scrap generated at the smelter/refinery and has the highest purity, usually recycled internally at the plant; "new scrap" is generated at downstream metal fabricators, trimmings, boring and croppings, which also usually is recycled at ...
Nchanga Copper Smelter Process Concept At Nchanga smelter the feed mixture isdirectly pr ocessed to blister copper in a flash smeltingfur nace (DBF). For slag cleaning twostage electric furnace process is applied. The smelter has concentrate smelting capacity of 849 000 t/a with the copper content of 311 860 t Cu/a.
In this work, a computational thermodynamic model of direct to blister copper smelting is described and then used to examine the differences between the smelting of a high iron chalcopyrite concentrate and a low iron bornite concentrate. The rapid decrease in copper recovery as the iron content of the concentrates increases is clearly seen.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper .

copper smelter utilises IsaSmelt smelting technology, and will process million metric tons of copper concentrate per year, with an output of 300 000 tons per annum of blister copper. The plant consists of an IsaSmelt furnace, a mattesettling electric furnace, four Peirce–Smith converters and two
Process Description Smelting Furnace (SFurnace) Dried concentrate and flux materials like silica sand are injected into Sfurnace through vertical lances and oxidized with oxygenenriched air to produce molten matte and slag, and their mixture overflows from the S .
The Outotec Flash Smelting Process is one of the world''s most commonly used processes for the production of primary copper and nickel. The process is based on our flash smelting principle, which utilizes the internal energy of the feed material for smelting, minimizing the need for external fuel and making the process very energy efficient.
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of % purity. Copper can be recycled indefinitely without the base metal being compromised ...
The "Mitsubishi Continuous Smelting and Converting Process" which we have evolved from years of research and production experience, is the world''s only commercially proven pyrometallurgical process to produce blister copper continuously from concentrates. 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 30
The matte produced by the flash smelting furnace is transferred to the Converter furnace. Oxygenenriched air is blown into the Converter furnace to oxidize the matte further to create blister copper with a grade of approximately 99%. Reaction in the converter Cu 2 S・FeS + SiO 2 + O 2 → Cu + 2FeO・SiO 2 + SO 2 + Reaction heat
Produce blister copper in a single flash furnace without the need for separate converting stages or ladle transportation. The Outotec Direct Blister Process offers new options for using different raw materials and optimizing plant layout while minimizing investment, operating costs, .
Matte mine furnaces with a copper content of 710% were sent to the Karabash and Kirovgrad smelters for further processing and obtaining refined copper. In 1940, tons of blister copper and 51 556 tons of sulfur were produced at the MSC, and in 1944 the production of blister copper increased by more than 9 times and reached 6, tons [4 ...

The primary smelter and refinery plant uses concentrate as a raw material, produces copper cathodes, sulphuric acid, and precious metals, and discards slag and offgases. Up to the production of blister copper in the converter, the main target is to remove iron and sulfur. After blister copper production, the purpose is to remove impurities.
