    Extraction Process of Aluminium from Bauxite Ore

    11/04/2016· In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it possible for them to be leached, or “digested,” at atmospheric pressure.

    Bulk minerals, mineral resources, Northern Ireland

    A comprehensive survey, published in 1912, was the first to recognise the lateritic origin of these iron ores and bauxite . The lateritic iron ores formed when the aluminosilicate lattice of pyroxene, olivine and feldspar broke down to produce clay minerals and iron and aluminium oxides. At ambient temperatures above 20ºC, silica passes into solution and is leached out of the soil profile. In

    Physicochemical Problems of Mineral Processing

    When processing the bauxite ores of the mass ratio of Al2O3 to SiO2 (A/S) = 4.99, the A/S of the final concentrate was 7.08 and the recovery of Al2O3 was 90.22%. When processing ores of A/S = 4.5, the A/S of the final concentrate was 7.04 and the recovery of Al2O3 was 92.16%. Thus, it can be seen that properties and behaviors of the ZMC reagent were remarkable and met the demands of the
