what is bauxite mining
Bauxite ore-which is commonly used in cement, iron and steel industries- generally has an oolit, massive, earthy, clay structure. Colors vary as green, brown, red, and gray. CIM Mining, presently capable of product supply 250,000/300,000 mtns per month and improves the production capacity constantly.
