  • Chapter 6 Copper Production Technology

    discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.The Copper Flash CC Smelting Process Total Materia,The production of copper in the flash smelting process is accompanied with a large amount of copper-rich slag, which has to be treated with the aim of copper recovery. Copper flash smelting consists of blowing fine, dried copper sulphide concentrate and silica flux with air, oxygen-enriched air or oxygen blast into a hot (≈1500K) hearth-type

The main application of copper anode is to use it as raw material in the process of electrolytic refining, to produce the electrolytic refined

  • USGS Minerals Information Copper

    Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.concentrating process copper,Copper Concentrating Smelting Process Copper ore concentration plants. The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final; Asian Metal Copper prices, news and research
