copper smelting process and methods,Copper Smelting Process - Furnaces Used, By-Products, and .May 26, 2011 . Historically, copper bearing ores contain only about 0.6% copper, the remainder being gangues or unwanted minerals. Chalcopyrite ore is in this range and can be mined by underground or surface methods. After extraction the ore is crushed and screened before being concentrated by a flotation process.Copper Smelting - IFCCopper Smelting. Industry Description and Practices. Copper can be produced either pyrometallur- gically or hydrometallurgically. The hydromet- allurgical route is used . and smelting. For converting, the Pierce-Smith and Hoboken converters are the most common processes. The matte from the furnace is charged to con-.
Chapter 82 - Metal Processing and Metal Working IndustryThis method is used in copper and nickel production. Iron, ferrochromium, lead, magnesium and ferrous compounds are produced by reduction of the ore with charcoal and a flux (line), the smelting process usually taking place in an electric furnace. (See also the Iron and steel industry chapter.) Fused salt electrolysis.Copper Processing - P2 InfoHouseThe water is recovered and recycled. One of two processing methods are used to refine concentrated copper. Pyrometallurgy, or smelting, is used on ore with copper sulfide and iron sulfide minerals. The concentrate is dried and fed into a furnace. The minerals are partially oxidized and melted, resulting in segregated layers.
