It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO 2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic

    Copper Refining - an overview | ScienceDirect Topics

    In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits

    Apr 09, 2010 Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised
