Thermal Processing: Pyrometallurgy—Non-ferrous

The non-ferrous converter, however, did not reach a similar barrier. Enriching the blast air, a few percent of oxygen had generally been sufficient for debottlenecking non-ferrous processes. This situation is rapidly changing and a new paradigm is emerging. Non-ferrous smelters are being squeezed by lower operating margins.
