Bayer process Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.

bauxite refinery process

Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived.

Bauxite Processing FEECO International Inc.

From processing bauxite for use in aluminum production, refractory, or proppants, we can develop a process solution that fits your needs, as well as engineer and manufacture the equipment needed. All FEECO equipment is engineered around the unique characteristics of the specific source of bauxite to be processed.

How Aluminum is Produced

The production of the metal Aluminum from the raw ore of Bauxite is a two stage process.

Lateritic Bauxite Deposits – Our Largest Source of Aluminum

Mineralogy of lateritic bauxite. The basic mineralogy of lateritic bauxites is similar throughout the world. The most sought after bauxite mineral is the aluminium hydroxide mineral gibbsite, Al(OH) 3. Although it has a lower aluminium content than some other minerals, gibbsiterich bauxite is cheaper to mine and process. Other aluminium minerals which may be present in bauxite …
