Bauxite Testing Laboratory; Bauxite is a sedimentary rock that serves as the world's principal source of aluminum. It appears in many forms, from soft earth to solid rock. It includes aluminum hydroxide minerals like gibbsite, boehmite and diaspore. Other materials present are iron oxides, clay minerals and insoluble materials.
Bauxite is used to produce alumina, which is then used to produce aluminum. Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process. The refinery processes used to produce aluminum generates about 2 – 2.5 tons of solid waste for …

In high-temperature digestion, weight% reactive silica needs to be determined by laboratory testing under digestion conditions. Another common parameter is the bauxite A/S ratio, which is (aluminum as Al 2 O 3)/(silicon as SiO 2). This is for quantifying the silica contamination in relative terms. Obviously, the silica problem is ore related.
