Chemetco - Wikipedia

Black copper was refined using oxygen, producing 98% copper, along with a zinc oxide residue and a slag containing lead, tin, nickel and a number of heavy metals. What Chemetco described as "zinc oxide" was extracted from furnace flue gases using a scrubber system. The zinc oxide, along with the slag, became a waste product.
