12 3 Primary Copper Smelting

Flash furnace smelting combines the operations of roasting and smelting to produce a high-grade copper matte from concentrates and flux In flash smelting dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both) into a furnace maintained at approximately 1000C (1830F)
