What is Bauxite?

What is Bauxite?

Bauxite is a highaluminumcontent rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is bauxite.

A process for removing silica from bauxite is disclosed. The method includes the step of mixing bauxite with a caustic liquor to form a mixture and to dissolve and stabilise at least a substantial part of the reactive silica from the bauxite. The caustic liquor is selected to have a high caustic concentration and a high alumina content.
