aluminum ore introduction

Aluminium | Geoscience Australia

Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. Properties

aluminum production capacity based upon announced production plans is expected to reach 61 Mt in 2015 compared with 45.3 Mt in 2006, which is an increase of 35%, or almost 3.4% per year. By 2025, aluminum consumption is likely increase more that 2.5 times to 120 Mt compared with 45.3 Mt in 2006. This represents a growth rate of 4.1% per year.

Bauxite: The principal ore of aluminum. - Geology

Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

An Introduction to the Electrolysis Process - AZoMining.com

To achieve this, the ore is crushed and roasted to convert sulfides into oxides and finally smelted to produce matte. It is then subjected to various refining processes, with the final step being the electrolysis. For example, bauxite has to be processed into pure aluminum oxide before it can be then converted into aluminum by electrolysis.

Primary Production | The Aluminum Association

Aluminum originates from bauxite, an ore typically found in the topsoil of various tropical and subtropical regions. Once mined, aluminum within the bauxite ore is chemically extracted into alumina, an aluminum oxide compound, through the Bayer process.
