Pyrometallurgy, extraction and purification of metals by processes involving the application of heat. The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas.

Pyrometallurgy an overview ScienceDirect Topics

Pyrometallurgy process cannot recover metals like Al and Fe since these are oxidized to metal oxides and shifted into the slag. It produces a large quantity of slag. It is impossible to recover some certain products such as plastic, ceramic, and glass since these are provided thermal energy to the burning process.

A process for enhanced removal of iron from bauxite

A process to remove iron from bauxite ore is described in which the ore is first finely crushed, calcined, and contacted with a reducing gas to convert iron present as very weakly magnetic goethite or hematite to magnetite or elemental iron. The ore is then passed through a magnetic separator to remove the iron.
