21st century plans for bauxite production expansion. A draft mining plan for bauxite was approved by the Vietnamese government in 2007. Vinacomin, a Vietnamese mining company, has laid out a plan for 6 bauxite mining projects covering over 1800 square kilometers in Vietnam's mountainous Central Highlands.The first two processing plants for the plan have been contracted to Chalco, a Chinese ...

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
