Returning to the overall process; that is the process for the sulfide ores and the oxide ore as I said are treated differently. Direct from the pit the oxide ore is piled onto large lined leach pads and the sulfuric acid.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and
The Kidd Creek copper/zinc mine is located near Timmins, Ontario, Canada. Along with copper and zinc it produces indium, silver-bearing slimes, nickel-copper carbonate, liquid SO2 and sulphuric acid.
Outokumpu flash smelting is a closed process which can achieve up to 99% capture of the sulphur-rich gases from the smelting furnace for the production of sulphuric acid. The technology was first introduced at Outokumpu's Harjavalta smelter in Finland in the late 1940's. Seventeen copper smelters world wide utilize Outokumpu flash smelting.

The to SO2, and the arsenic, along with the other impurities, is SO 2 is converted to SO 3 in the converter, and the SO 3 is volatilized into the gas …
The first acid plant was commissioned in 2005 with a capacity of 100tpd at Usoke Ave. The sulphuric acid produced at the Usoke compound is used in the leaching of mined ore for the production of copper cathodes and cobalt carbonate.
This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process. In Latin America, the total is closer to 40% whereas in the United States the total is approaching 30%.
ACID SUPPLY. The source of sulphuric acid for leaching is usually a major consideration for small plants. If the plant is located in an area where acid can be purchased at low cost, one of the greater items of capital expense can be avoided.

The final phase of the solvent extraction process employs a strong acid to strip the copper from the organic solution, producing a blue, enriched copper-bearing solution that is treated at an electrowinning plant.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
In this process, copper and precious metals remain as a pyrophoric residue that re-quires separate treatment. Use of electrical cells equipped with inert cathodes is the most com-mon technology for nickel refining. Electro-winning, in which nickel is removed from solution in cells equipped with inert anodes, is the more common refining process. Sulfuric acid Pollution Prevention and Abatement ...

Figure 2 – CESL Process Commercial Development Plan It is anticipated that the 10K plant will operate for 3 years, initially processing chalcopyrite copper concentrate and subsequently bornite concentrate.
hydro- and pyrometallurgical processing to refin-ing, copper production can have significant ad-verse impacts on air quality, surface and ground- water quality, and the land (see figure 8-1 ). While these impacts can be severe when the materials handled include toxic or hazardous substances (e.g., ores with a relatively high concentration of arsenic), they also can be modest due to techno ...

Processing sulfur technological gases formed in pyro-smelting copper concentrate processing in a smelting furnace and the converters in metallurgical production results in sulfuric acid production.
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes.
Copper Smelting Industry Description and Practices Copper can be produced either pyrometallur- gically or hydrometallurgically. The hydromet-allurgical route is used only for a very limited amount of the world's copper production and is normally only considered in connection with in-situ leaching of copper ores; from an environmen-tal point of view, this is a questionable produc-tion route ...
