What is a Copper Slag with pictures InfoBloom

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore they produce a large volume of non-metallic dust soot and rock. Collectively these materials make up slag which can be used for a surprising number of applications in the building and industrial fields.

Copper Smelting Slag Recovery

Copper mainly dwells in the slag in the form of bornite chalcocite chalcopyrite and metallic copper. The rest are iron minerals like magnetic iron ore metallic iron and gangue like fayalite hedenbergite and amorphous phase matter. Such slag can be concentrated by separation and enrichment to obtain copper concentrate.
