Copper Production Processes :: Total Materia ArticleCopper extraction

Several different processes can be used for copper production The old traditional process is based on roasting, smelting in reverbatory furnaces or electric furnaces for more complex ores, producing matte and converting for production of blister copper which is further refined to cathode copper SoCopper extraction refers to the methods used to obtaining copper from its or The conversion of copper consists of a series of chemical, physical, and electrochemical process.

Chapter 6 Copper Production Technology

Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper or With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained .The matte layer refers to the iron-copper sulfide mixture which sinks to the bottom The slag, which refers to the remaining impurities, floats on top of the matte The slag is discarded on site or sold as railroad ballast and sand blasting grit Sulfur dioxide gases are also collected and made into sulfuric acid for use in hydrometallurgical leaching (discussed below) or sold off-site.

METALLURGY OF COPPER-EXTRACTION OF COPPER-BLISTER COPPERGłogów Copper Smelter and refinery

Blister copper is refined by electrolysis Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathod The cathode plates are coated with graphite in order to remove depositing copper The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity Optimum potential difference is 13 volt for this .Converting, ie the processing of copper matte in a converter furnace (oxidisation of sulphides) to obtain crude copper with 985% Cu content; , The production at the Głogów II copper smelter is based on modern one-stage flash furnace smelting technology, in which blister copper is produced directly from dried concentrate The production process consists of: Concentrate smelting to obtain.

Copper Production: How Is Copper Made?

Copper is typically extracted from oxide and sulfide ores that contain between 05 and 20 percent copper The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors Currently, about 80 percent of global copper production is-11-08 Nickel - History, Production, Applications, Pricing and Trading - Agiboo Nickel is a metal used most commonly as an alloy to improve other metals copper but instead found a silver-white metal which he named nickel The extraction of nickel from the sulfidic ore requires a different method After the mining and processing of either the lateritic ore or sulfidic ore there remains nickel matte.

123 Primary Copper SmeltingCopper Concentrates

Metallurgical problems, however, led to the operation of these reactors for the production of copper matte The Noranda process uses heat generated by the exothermic oxidation of hydrogen sulfide Additional heat is supplied by oil burners or by coal mixed with the ore concentrat Figure 123-2 illustrates the Noranda process reactor Flash furnace smelting combines the operations of .Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper The production of concentrates.

How copper is made

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 increasedOutokumpu Oy has intensively studied the production of high-grade copper matte in a flash smelting furnace since the s Blister copper was first produced in the pilot furnace of the Metallurgical Research Centre at Pori in and the first commercial plant for direct blister production was.

Definitions

Blister copper consists of an impure form of copper produced by blowing air through molten copper matte During the conversion process, sulphur, iron and other impurities are oxidised The copper content is normally about 98 % by weight It is the product of a converting furnaceCharacterisation of the substance Substances produced during the production of copper are included in the scope of the Copper REACH consortium and commonly referenced as Copper intermediat.
