The history of making blister copper in an Outokumpu Flash Smelting Furnace dates back to the late 1960''s, when Outokumpu first piloted the Outokumpu Direct Blister (ODB) process.
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. This paper is a survey on the effect of oxygen potential or matte grade on the metallurgy of smelting copper concentrates in a flash smelting ...
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.
Chinese copper smelter Jiangxi Copper and Zambian blister copper producer Chambishi have agreed refining charge (RC) of 128/mt for 2020 blister copper supply, SMM learned. This marked a decline of 37/mt, or % from 165/mt for 2019, pointing to strong expectations of tight supply of blister copper .
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.

Nov 28, 2019· Copper rose steadily through November on the back of positive developments in the USChina trade war and continued civil unrest in Chile. Declining stock levels have also supported prices. However, an underlying slowdown in enduse demand endures, despite .
Flash furnace smelting combines the operations of roasting and smelting to produce a highgrade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000°C (1830°F).
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
Outotec Direct Blister Flash Smelting for copper With this process, blister copper is produced directly in a flash smelting furnace without the need for separate converting phases and ladle transportation. This method opens up the possibility to use different raw materials and optimize plant layout while minimizing capital investment,
Dec 01, 2013· Jinliang WANG, et al/Trans. Nonferrous Met. Soc. China 23(2013) 3799Ã3807 3806 5 Conclusions 1) According to the innate characteristic of four types of furnace, a thermodynamic model of the copper flash continuous smelting (CFCS) was established by building the multiphase equilibrium model of the flash matte smelting process (FMSP) and the ...
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 ...
Aug 23, 2017· Flash smelting accounts for over 50% of copper matte smelting globally. It involves blowing oxygenrich air, dried CuFeS concentrate, silica flux and recycled materials into a .
May 17, 2018· Trial operations from next month should mark the start of a new wave of copper smelting and refining capacity in China, which should boost copper concentrate imports but could also cap growth in import demand for cathode and blister copper. At million tonnes, China''s copper concentrate imports in the first quarter 2018 were up % and ...
Under this approach, the PEA also includes the construction of a directtoblister flash copper smelter at the Kakula plant site with a capacity of one million tonnes of copper concentrate per annum to be funded from internal cash flows. This would be completed in year five of operations, achieving significant savings in treatment charges and ...
Feb 13, 2004· China imports mainly No 2 copper scrap and the lowerquality No 6 and No 7 grades, including wire, cable, small motors and power generators that contain less than 80 percent copper metal. Lion said smelters had little choice but to pay higher prices for prompt delivery of copper scrap. "They cannot turn their back on the market for the quite ...

Gécamines (La Générale des Carrières et des Mines), is a stateowned mining company in the DRC. Its principal products are copper (which often accounted for 50% of export earnings), cobalt and zinc. Copper mines in which Gécamines has a major interest include Kambove, Kipushi and écamines also owns a copper smelter at Lubumbashi and a hydrometallurgical plant at .
Dec 06, 2016· In 2015, global blister production from smelters totalled contained copper against total electro refined production of 18Mt of cathode copper. The shortfall was filled by highgrade scrap; the recovery of copper from highgrade scrap is estimated to have totalled, and the intermediary market for copper blister was therefore ...
Nov 20, 2019· Established in 1958, Yunnan Copper is China''s third largest producer of copperbased on total capacity. It''s smelter in Qingyuan, Guangdong province, is a joint venture between Yunnan Copper and China Nonferrous Metals Group, which mainly processes blister from the Chambishi smelter in Zambia.
