    Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters

  • Blister Copper an overview ScienceDirect Topics

    The product of Equation (13.5) is the next stage of refinement called blister copper, and it generally contains precious metals as well as copper. Blister copper is subjected to fire refining. This involves blowing the copper with air to oxidize reactive metal impurities to slag.

  • Blister copper metallurgy Britannica

    In copper processing: Roasting, smelting, and converting remaining values), leaving a “blister” copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.

  • METALLURGY OF COPPER-EXTRACTION OF COPPER-BLISTER

    Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. 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.

  • Copper Production: How Is Copper Made? ThoughtCo

    Sep 26, 2019· The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

    The Contimelt process is based on two interconnected furnaces, including a heart shaft furnace where high-grade scrap, blister copper and black copper are smelted. Oxy-gas burners supply heat for melting. The molted copper flows to a cylindrical furnace, where it is deoxidized using natural gas and cast in anodes (Figure 7.1).

  • Copper processing Roasting, smelting, and converting

    The final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels. This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining.

  • Cementation process Wikipedia

    The cementation process is an obsolete technology for making steel by carburization of iron.Unlike modern steelmaking, it increased the amount of carbon in the iron. It was apparently developed before the 17th century. Derwentcote Steel Furnace, built in 1720, is the earliest surviving example of a cementation furnace.Another example in the UK is the cementation furnace in Doncaster Street

    The air is blown through the molten matte. Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten copper. The copper so obtained is called "Blister copper" because, as it solidifies, SO2 hidden in it escapes out producing blister on its surface. 2CuFeS2 + O2 è Cu2S + 2FeS + SO2. S + O2 è SO2. 4As + 3O2 è

  • How copper is made material, used, processing, steps

    Even though copper blister is 99% pure copper, it still contains high enough levels of sulfur, oxygen, and other impurities to hamper further refining. To remove or adjust the levels of these materials, the blister copper is first fire refined before it is sent to the final electrorefining process.

  • Copper Smelting Process Furnaces Used, By-Products, and

    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

  • Copper Mining and Processing: Processing of Copper Ores

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
