Quality evaluation of bauxite

The quality of bauxite will affect the control of production technology conditions, equipment capacity, energy consumption and product quality. The evaluation indexes of bauxite quality mainly include aluminum content, aluminum to silicon ratio of bauxite and type of bauxite.

1.Alumina content. The alumina content in bauxite is usually between 45% and 75%. The higher the content of alumina, the better the product quality;

2.The ratio of aluminum to silicon of bauxite. The higher the ratio of aluminum to silicon, the better the quality of bauxite. At present, industrial production of alumina requires bauxite with an aluminum to silicon ratio of not less than 3.0-3.5.

3. Type of bauxite. Different types of bauxite, the technical conditions adopted are also different.
