The main raw materials of copper flash smelting are a copper concentrate, b silica flux, c air, d industrial oxygen. the reactions in the flash furnace may be represented by equations of the type reactions 1 and 2 are strongly exothermic. they provide most or all of the energy for heating, melting and superheating the furnace ...
May 01, 2019nbsp018332as a direct-to-blister copper flash smelting slag contains important levels of copper 14 and lead 24 it is subjected to a process of high temperature reduction. to recover copper as well as lead the slag is subjected then to a process of decopperization by reducing the oxide metal compounds in an electric furnace.
We dry it and send it into a flash-smelting furnace, which separates it into several products, including a copper matte that is 70 percent copper. after the copper matte cools, we feed it into several furnaces that remove most of the remaining impurities, achieving 99.6 percent purity. we then cast the copper into 750-pound anodes.
Copper slag properties in reverberatory furnace smelting, flash smelting, and other processes are similar. a typical smelting slag contains approximately 3045 feo, 3040 sio 2 , 510 al 2 o 3 , 26 cao, and 24 mgo kokal, 2006 .
