Pyrometallurgy produces a sulfur-deficient matte that can be further processed using leaching, solvent extraction, and electrowinning. High-purity nickel is produced after electrorefining or the vapometallurgy-based carbonyl process. Nickel is primarily used in the production of superalloys and stainless steels.

2018-1-12 Mineral processing is a major division in the science of Extractive Metallurgy. Extractive metallurgy has been defined as the science and art of extracting metals from their ores, refining them and preparing them for use. Within extractive metallurgy, the major divisions in the order they may most commonly occur are, Mineral Processing

Pyrometallurgy operations such as smelting and roasting involve processing of ores and other materials at high temperatures (i.e., often > 1000 °C) and in the absence of aqueous media. Environmental issues related to pyrometallurgy involve gaseous and particulate emissions (e.g., SO 2 , CO 2 , CO, Hg, As-, Sb-, Se-, and Te-oxides).

2020-9-8 In pyrometallurgy, an ore is heated with a reductant to obtain the metal. Theoretically, it should be possible to obtain virtually any metal from its ore by using coke as the reductant. For example, the reduction of calcium metal from C a O ( s): (23.2.7) C a O ( s) + C ( s) → Δ C a ( l) + C O ( g)
