7.3.3 Nickel and copper-nickel slag. Nickel production from high-magnesium nickel oxide ores follows a pyrometallurgical process including prereduction, smelting in a blast furnace, and nickel enrichment refining. 71 During the smelting stage, besides the nickel alloy
Copper Refining. Copper is widely used to make electrical wiring and in other applications that utilize its high electrical conductivity. Crude copper, which is usually obtained by pyrometallurgical methods, is not suitable to serve in electrical applications because impurities greatly reduce the metal's conductivity.
lead production, the pyrometallurgical techniques being more widely employed , . ... The principal impurities which are removed in secondary lead refining are copper, tin, antimony and arsenic. Copper can be removed in a similar fashion to that outlined for primary lead. Some companies use iron pyrites and Sulphur which works at a higher
Copper and nickel are extracted by the sulfuric acid-leaching route. Leached residue makes up the high-grade PGM–Cu concentrate containing 30–65% PGEs. The concentrate is further processed in steps of electrolytic refining (electrolysis), pyrometallurgy, and selective-solvent extraction refining for final separation of the pure precious metals.

Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used ...
When sufficient copper has been cemented out, the copper-rich iron is put into the smelter together with the ore concentrates for copper recovery via the pyrometallurgical route. In the SXEW process, the pregnant leach solution (PLS) is concentrated by solvent extraction, which extracts copper but not impurity metals (iron and other impurities).
pyrometallurgy[¦pī·rō′med·əl‚ər·jē] (metallurgy) Processes that use chemical reactions at elevated temperatures for the extraction of metals from raw materials such as ores and concentrates, or for the treatment of recycled scrap. Pyrometallurgy the science and technology of high-temperature metallurgical processes. Pyrometallurgy is the ...
Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.
Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs). 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 ...
