Copper Smelting Slag Recovery- - metalcess

Copper Smelting Slag Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at 0.3-3%. The slag may also contains lead zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.

RECOVERY OF IRON FROM COPPER FLASH SMELTING

2015-9-7  The flash smelting process has been used in copper industry for a number of years and has replaced some conventional copper smelting processes in Chile. The high copper content in the slag in this process, require a further cleaning in an electric furnace. Also, the converter and fire refining slag are recycled to the smelting process to increase the matte grade.Flash smelting slags are cleaned in an electric arc furnace, where coke is used as reduct-ant and the copper content of the final slag decreases [1, 2]. Also, several practices of recovering metals from slags have been reported [3, 4, 5, 6, 7]. However, copper slags con-tain other metals with commercial value than copper, such as iron, among others which can be recovered. Thus, the process used to recover metals from slag consisting in reducing the slag
