Product Description Refractory Grade Al2O3 65-88% Raw Bauxite Ore / Calcined Bauxite PriceBauxite is one of the principal ore of aluminum.Bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 850C to 1600C) .this can removes moisture thereby increasing the alumina content.Classification Introduction:1.Classified according to the type of bauxite raw materials: (1) raw bauxite, alumina original ore (natural sedimentary rock class). (2) the calcined bauxite, the raw bauxite after high temperature calcination (1200 ~ 1700 oC)2.Calssified according to the different calcining kiln where the bauxtie is divided into: (1)Shaft kiln bauxite (2)Rotary kiln bauxite (3)Round kiln bauxite3.Calcined Bauxite according to different uses for division: (1) the refractory grade bauxite (2) the grinding grade alumina (3) the welding grade bauxiteBauxite has a lot of different specifications likeGranular ( 0-1mm 1-3mm 3-5mm 5-8mm) Powder ( 200mesh 325mesh )and big lump , the Al2O3 from 65-90%we can also produce according to customers special requirement Al2O3 contentFe2O3 contentSiO2 contentTiO2(%)bulk DensityRefractoriness 90%1.5max3.5max3.8max3.35min1790oC min85%2.0max8.0max4.0Max3.2min1790oC min80%2.5max 10.0max4.5Max3.0min1790oC min75%3.0max 10.0max5.0Max2.9min1770oC min70%3.5max 10.0max5.0Max2.8min1770oC min65%4.0max10.0max5.0Max2.7min1770oC minApplication of our calcined bauxiteRaw material for High Alumina brick;Raw material for Refractory castable;Raw material for Ramming mix;Raw material for Nozzle;Raw material for slide gate block;Raw material for Refractory motar;
