    Possibilities for minimizing copper losses in converter slags include: (1) settling the molten slag to recover entrained matte and copper, (2) smelting the slag with a suitable reductant to recover a copper-iron alloy or a low-grade matte. (3) beneficiation of slags by magnetic separation, and. (4) treatment of the slag by flotation.
