Bauxite | Guyana Then And Now
The making of Alumina occurred at the Alumina plant located at Speightland. Bauxite is first processed to make alumina, or aluminum oxide, a white granular material. Alumina is lighter than bauxite because the water has been removed, and it flows readily in the processing plants, unlike bauxite which has a sticky, muddy consistency.
Alumina Limited
Bauxite is generally washed, ground and dissolved in caustic soda (sodium hydroxide) at high pressure and temperature at an alumina refinery. Approximately four tonnes of bauxite produces one tonne of alumina and approximately two tonnes of alumina are required to produce one tonne of aluminium.
