Copper smelter process

carded slag from the smelter. Discard slag may contain 0.5–0.7% copper and is frequently used as construction material or for sandblasting. Leaching processes produce residues, while ef-fluent treatment results in sludges, which can be sent for metals recovery. The smelting process typically produces less than 3 tons of solid waste
