Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal …
