This has allowed the operators to apply the recipes originally developed for smelting concentrates containing iron minerals and rust. It is this same need to oxidise iron that mitigates against the use of soda ash which is a mild reductant, as a flux. (The tendency for soda ash to cause foaming due to rapid gas generation is also undesirable).

smelting | Definition & Facts | Britannica

In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out at the bottom. A second heat treatment, in another (converter) furnace, is necessary to remove the iron from the matte.
