As one of leaders of copper grade refining charges industry, SBM always seeks innovation & excellence.
Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters.

The high-grade manufacturing wastes require only reclamation, melting, casting, and marketing, which costs about $0.2/kg of copper. Low-grade scrap, on the other hand, requires reclamation, sorting, smelting, refining, and marketing, which costs about $0.6/kg of copper (Table 22.2). Intermediate- grade scrap treatment lies between these two ...
