12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.

General Information The Głogów Copper Smelter comprises two separate process plants – Głogów I and Głogów II. The technology used to process copper concentrates in flash furnaces results in the final product – electrolytically refined copper in the form of cathodes with a 99.99% Cu content, registered on the London Metal Exchange as grade A according to BS EN 1978:1998 and on the ...
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.
The Outotec Direct Blister Process offers new options for using different raw materials and optimizing plant layout while minimizing investment, operating costs, and the environmental impact even further. Results in high recovery of copper and other valuable metals ; Ensures low investment and operating costs for smelter and acid plants ...

ducing copper: the direct and indirect costs in-curred in mining, concentrating, smelting, and refining copper. They include transportation to the mill, smelter, and refinery, and metallurgical processing of the byproducts. Some estimates of operating costs also include the freight charges for transporting the refined copper to market.4
The TCs are charged in US$ per tonne of concentrate treated and RCs are charged in cents per pound treated, denominated in US dollars, with benchmark prices set annually by major Japanese smelters. The customer in this case can be a smelter, who on-sells blister copper ingots to a refiner, or a smelter-refiner which is vertically integrated.
Since the first industrial application in 1940s, flash smelting has been developed for other applications than copper matte smelting, including the oxygen enriched smelting, continuous converting to blister copper with low sulphur concentration, and direct-to-blister smelting.
Copper concentrates which have high silica but low iron contents are difficult to smelt using conventional two stage smelting processes. Direct to blister smelting is possible using either iron ...
Copper Smelting Process: Historically, the most abundant copper bearing ore was called chalcopyrite, CuFeS 2. This ore is first enriched by a process called flotation. Powdered ore is mixed water as a slurry and then further mixed with oil and a chemical called amyl xanthate.

OF AN IDEAL SMELTER Aerial view of Naoshima smelter and refinery The Mitsubishi Process: A step ahead of the rest Copper has been recognized as a valuable resource since ancient times. Mitsubishi Materials has sought to optimize the smelting of this valuable resource for many years. We believe the ideal smelter should be environ-
Feb 09, 2017· Various slag systems have been considered for direct-to-blister smelting. They have been evaluated computationally, using the MPE thermodynamic modelling package, and practically, at pilot scale. The lime-silica-iron oxide slag was found to have the lowest slag make, lower dissolved copper and hence lowest copper losses.
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.
A unique aspect of the smelting process is that most of the energy for smelting the copper is provided by the oxidation of iron and sulfur in the feed materials. In spite of this energy efficiency, the smelter still requires large quantities of fossil fuel and electric power.
Sterlite Copper at a Glance. Sterlite Copper represents the Copper Unit of the Sesa Sterlite Limited. Sterlite Copper Unit operates a 400,000 Metric Tonnes Per Annum(MTPA) Copper Smelter with associates facilities such as Refinery and Copper Rod Plant, Sulphuric Acid plant of more 12,00,000 MTPA and a Phosphoric Acid of 220,000 MTPA at Thoothukudi, Tamil Nadu.
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,
Copper smelting is typically a two-stage process, with a feed of copper ore or concentrate to a roaster or sinter plant to agglomerate the concentrate and remove some sulfur. This material, along with fluxing minerals and a fuel such as coal or oil, is then fed to a furnace where a copper matte is produced.
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 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...
The process is a continuous, multi-step process which produces blister copper from concentrates in three interconnecting furnaces. Concentrate and oxygen-enriched air (30-35% O 2 ) enter the smelting furnace through vertical lances and are smelted to produce a matte of 65% to 69% Cu and low-copper …
Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities.
copper smelter plant direct to blister process. outotec direct blister copper smelter plant process . Copper ore a valuable mineral source for all countries. Copper ore is an ore which can produce copper metal by crushing in ore crushing plant, grinding in Ball mill and smelting in .
In fact, a single-step direct copper smelting process with a discardable slag is theoretically possible at 1200 °C only at reduced pressure (e.g., oxidation at C′). PSDs for this system may be drawn for other temperatures and fluxes to suggest better conditions for a direct smelting process.
A commercial plant has been in operation since 1978 at Glogow in Poland, to smelt a low iron-sulfur, carbonaceous, comparatively high-copper concentrate directly to blister. Direct smelting to blister is only practical where the levels ofPb, As, Bi, etc., in the concentrate are low.
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. ...
