A survey on cobalt metallurgical processes and its application

The Cobalt (Co) is the thirtieth most abundant and a first-roll transition metal, accounting for around 29 ppm of the earth's crust, roughly equivalent to scandium. Co contains minerals within its oxide like nickel, copper, and Manganese (Mn), Co is often used in sample preparation schemes, like Cobalt (II) oxide (CoO), and Cobalt (III) oxide ...

Pyrometallurgy | Metallurgy for Dummies

Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).

The Extraction of Copper

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Strategies for arsenic pollution control from copper pyrometallurgy

In addition to primary copper-phase chalcopyrite, some secondary copper sulphides and silicate minerals were also observed, mainly coming from recycled materials. Arsenic is primarily present as copper-arsenic sulphides in the total feed because copper-arsenic sulphides are chemically similar to copper sulphide minerals (Long et al., 2012).
