    Ammonia leaching of slag from directtoblister copper

    Aug 25 2020 Smelting of copper concentrates in a flash furnace directly into a copper blister results in the production of slag with high copper and lead content. The recovery of these metals is carried out in an electric furnace from which copper–lead–iron metallic alloy is then processed in a converter furnace. In the presented work copper and lead extraction studies were carried out by.
