Chapter 2. Production and Processing of Aluminum

The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

Smelting

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Chapter 8 Environmental Aspects of Copper Production

Uncontrolled copper smelting processes emit large quantities of particulate matter, trace ele-ments, and sulfur oxides, which can have adverse effects on human health. Sulfur dioxide (SO 2), and the sulfates and sulfuric acid aerosols it forms in the atmosphere, can be lung irritants and ag-gravate asthma. Estimates of the magnitude of

[PDF] Ilmenite smelting: The basics | Semantic Scholar

This paper briefly reviews the principles of the ilmenite smelting process. Ilmenite has the nominal composition FeO.TiO2. South African beach-sand ilmenites are close to this nominal composition, with the main impurities being MnO, MgO, SiO2 and Al2O3 (amounting to some 3% of the mass of the ilmenite).
