    (PDF) Reduction of Reactive Silica from Bauxite

    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. The small particle size and low silica content make our Bauxite one of the highest in value worldwide.During the crushing operation, the two rolls rotate toward each other, resulting in crushing. The feed particle size determines the type of rollers used. Rollers with teeth are able to grip large particles, making it possible to crush blocks of considerable size in rolls of moderate diameter.
