Bayer Process Plants Noranda Alumina

A Bayer process plant is principally a device for heating and cooling a large recirculating stream of sodium hydroxide solution through a temperature range of up to 500oF per cycle. Liquor flow rates of 5,000 to 10,000 gpm are common in the newer plants. Bauxite is added at the high temperature point, red mud is separated at an intermediate ...

Bayer process - Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.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. The aluminium oxide must be purified before it can be refined to ...
