Product Description Product DescriptionCalcined bauxite is one of the principal ore of aluminum. Calcined bauxite is obtained by calcining (heating) superior grade bauxite at high temperature (from 850oC to 1600oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57% to 58% in raw bauxite, calcined bauxite has an alumina content of 84% to 88%. The calcined bauxite can be processed into bauxite sand and bauxite powder of different particle sizes, both of which can be directly used as refractory sand. It has a very high status in the field of refractory materials. We are not only bauxite supplier, but also your loyal partner who can provide qualified products.

Calcined Bauxite for precision castingThe alumina clinker which is processed into fine powder and made into cast mould can be used in military, aerospace, communications.Calcined Bauxite for aluminum refining IndustryIt can be used for national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities. Calcined Bauxite for high friction surface coatingCalcined bauxite has been the most commonly used aggregate material used for High Friction Surfacing.The inherent nature of Calcined Bauxite resists shear stresses that lead to polishing of the road surface.Besides, calcined bauxite also can be used in fire bricks, refractory cement, castable, welding flux, etc. Packaging & Shipping FAQWhat is your MOQ?One full container (25-28tons). More quantity you required , better price we can offer for you.What is the leading time?That depends on order quantity. Generally it takes 10-15 days for one full container. How can I get samples to check the quality?We can provide the samples free for you, but the express cost will be on your account. What is your payment term?50% T/T in advance, and balance payment at sight copy of BL. Letter of credit is also available.
