bauxite processing and by products

Products - Bauxite Noranda Bauxite

It can be used in cement, chemicals, cosmetics, soda cans, appliances, and many other aluminum products. At Noranda Bauxite, we mine and ship high-quality bauxite with low-cost processing characteristics. Our bauxite has a silica content of less than 2% and a small particle size. This means the process for crushing and grinding is not as intensive.
