bauxite extraction process

bauxite separation process

Bauxite is the main source for the production of alumina and metal aluminum by the Bayer process. Limestone is an impurity associated to bauxite due to geological and morphological conditions prevailing during its formation. Experimental work has shown that limestone can be easily removed from bauxite using magnetic separation techniques.
