Bayer Process Bauxite Stockpile

An Information System for a Bauxite Mine

Information System for a Bauxite Mine 92 The refinery uses the Bayer process (Habashi, 2005) to convert the bauxite ore to pure alumina. Efficient operation of the refinery depends upon the bauxite feed having consistent grade.

Production – Red Mud Project

13.07.2005· The Bayer process, as it has become known, is used for refining bauxite to smelting grade alumina (aluminum oxide), the precursor to aluminium. Typically, depending upon the quality of the ore, between 1.9 and 3.6 tonnes of bauxite is required to produce 1 tonne of alumina. The Bayer process is a cyclic one and is often called Bayer cycle.

What Is the Bayer Process?

The Bayer process is a chemical process widely used in the industry to produce alumina from bauxite. Invented by Austrian engineer Karl Joseph Bayer in 1887, the basic principle is to convert aluminum hydroxide to sodium aluminate with concentrated sodium hydroxide solution, and to re-precipitate aluminum hydroxide by diluting and adding aluminum hydroxide seeds.

The Chemistry and Processing of Jamaican Bauxite

13.06.2014· The Chemistry and Processing of Jamaican Bauxite. The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.
