Pyrometallurgical processes are a primary method to recover PGMs from spent catalyst.3 In general, they can be divided into three groups: smelting, chlorination, and sintering processes. Smelting Process. The smelting process is the mostly commonly employed approach for concentrating PGMs in many companies with …
Manganese is considered a relatively rare metal as concentrations of it in ore of commercial importance are geographically limited. In nature, manganese is found in the form of oxides, carbonates, and silicates. Manganese ores are complex in the sense that they not only consist of a complex oxide mineral assemblage but these minerals are …

The difference between the process and plasma arc smelting process is that the smelting operation was performed at a temperature of 1450 °C using a conventional electric arc furnace. In the process, Pt, Pd, Rh recovery was over 99%, 99%, 97%, respectively, and PGM content in the resulting slag was about 1 g/ton.

Overview of the steel production process. Most steel in South Africa is produced via two basic routes: The Blast Furnace-Basic Oxygen Furnace (BF-BOF) route and the Electric Arc Furnace route (EAF). Blast furnaces produce iron from iron ore. In a second step a basic oxygen converter turns iron, with some additions of scrap, into steel.
