Calcined bauxite is an important raw material for two main markets: refractories and abrasives. Smaller volumes are consumed in other applications including proppants, welding fluxes, and antiskid surfaces. While the process of calcining bauxite for each of these applications is fundamentally the same.
Bauxite does not have a specific composition. It is a mixture of hydrous aluminum oxides, aluminum hydroxides, clay minerals, and insoluble materials such as quartz, hematite, magnetite, siderite, and goethite. The aluminum minerals in bauxite can include: gibbsite Al(OH) 3, boehmite AlO(OH), and, diaspore, AlO(OH).
Bayer. Today the Bayer process dominates the production of alumina as it is the lowest cost production route. The process uses a recirculating volume of concentrated caustic solution to dissolve the alumina minerals, separate them from still solid impurities, and then reprecipitate alumina trihydrate.

The chemical and physical properties of bauxite residues are determined by the nature of the bauxite and the effect of the Bayer process. The technology and operating procedures at individual refineries will impact the water content and pH value of the material being discharged two key factors in bauxite residue management.
Basic calcining process. Petroleum coke calcining is a three step process, including drying, devolatization and densification. The coke calcining process is a timetemperature function, conducted in an oxygen deficient atmosphere. Important control variables are heating .

Mar 23, 2016· 3) PREPARATION OF FUSED ALUMINA Fused alumina is trade names of Alundum and Aloxite. Fused alumina is used to made abrasive grains. Before processing, bauxite, the crude raw material, is calcined at ~950°C to remove both free and combined water. The bauxite is then mixed with ground coke (~3 %) and iron borings (~2 %) in a pottype, electricarc furnaces for 24 hours at 2000oC. .
