Pyrometallurgy Metallurgy for Dummies

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 gas phase may also be used to advantage,

Copper: smelting, producing and classification-Metalpedia

Pyrometallurgy usually adopts original ore, in which its content can reach 20%-30% after mineral processing. Copper concentrate is put into an airtight blast furnace, reverberatory, electric furnace, or flash furnace for matte smelting. The output of molten matte is then put into the converter for converting into a blister copper, and next into another kind of reverberatory.
