Product Description
Mingyue Bauxite and Calcined Bauxite:
Mingyue Bauxite, ie. bauxite ore, whose main content is Aluminium oxide with, who is department of hydrated
alumina containing impurities in appearance of earthy mineral;
Mingyue Calcined Bauxite is burnt bauxite, who is used for producing the existing uneven materin in nature --
alumina and aluminium. The purpose of calcining bauxite is to remove crystal water and improve the content of alumina.
