12.3 Primary Copper Smelting
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 1000°C (1830°F). As with the Noranda process reactor, and in contrast to reverberatory and electric furnaces, flash furnaces use the heat generated from partial

Copper Smelting Process
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 …

Numerical simulation and optimization of flash reduction of iron ore
During the flash ironmaking process, fine iron concentrate and flux powder, accompanied by reductive gas, are injected into a flash furnace. In the process of falling into the furnace, the fine iron concentrate is heated and drastically pre-reduced by the high-temperature reductive gas within a few seconds of flight time.
