Chemical Grade Bauxite composition offered by us: A12O3 58% (min.), Fe2O3 % (max.) Steel and Cement Industry use # Bauxite should have A12O3 40% SiO2 5% and Fe2O3 30 – 40% bauxite for use in cement industry. In the steel industry metallurgical grade bauxite is used as a flux as partial replacement of fluorspar.
Bauxite is transported from the mines by rail to Kwinana and by overland conveyor to Pinjarra. The close proximity of mine to refinery lowers operational costs. Bauxite from Huntly is low in alumina grade and low in reactive silica. This results in low consumption of .
over 35% of global metallurgical grade alumina production. This update of the Alumina Technology Roadmap has for the first time benefited from collaboration with the Chinese alumina industry. A meeting of the IAI Bauxite Alumina Committee was held in Zhengzhou, China in April 2010, hosted by Chalco''s Zhengzhou Research Institute.
Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution at a temperature of 150 to 200 °C (300 to 390
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide, (alumina), Al 2 O 3, the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can .
