Following mineral beneficiation, which removes the non-ore components, the ore itself must be broken down into its component value metals. Marine minerals can contain up to half a dozen economically desirable metals. In order to separate these metals individually, a reduction process must occur to break the chemical framework of the ore.

Roasting, smelting, and converting are pyrometallurgical process steps that are based on the relative affinities of metals for sulfur and oxygen. A typical process flowsheet is shown in Fig. 1. Iron sulfide is primarily converted to oxide in roasting.

Pyrometallurgy an overview ScienceDirect Topics

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.
