The next stage, smelting, is a process of heating and melting the copper concentrates to cause a chemical reaction, which removes the copper from other elements in the ore. At the smelter, we produce large 750-pound anodes and transport them by rail to the Refinery. The copper is 99 percent pure at this stage.

Copper Smelter . 2015-4-10 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.

Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. 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.
Apr 09, 2010 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
4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
Flash converting closely resembles flash smelting. Flash smelting is a closed process and, consequently, off-gas emissions can be efficiently controlled. Flash converting had its first application in the expansion and modernization of Kennecotts copper smelter near Salt Lake City, Utah, which was implemented during 1992-95.

furnace process rate is controlled by the proportion of coke in the charge and by the air flow through the tuyeres in the floor of the furnace. The charge descends through the furnace shaft into the smelting zone, where it becomes molten, and is tapped into a series of settlers that allow the separation of lead from slag.
Flash smelting can be autothermal if appropriately adjusted flow rates of oxygen are used. Flash smelting process yields a high grade of matte. A matte, produced in the flash smelting furnace, nevertheless, has to be transported to the converters and oxidized to obtain blister copper employing the same two-stage, multi-cycle, batch operation as ...
