The aluminium production process starts with the mining of bauxites an aluminium rich mineral in in the form of aluminium hydroxide About 90 of global bauxite supply is found in tropical areas ALUMINA PRODUCTION
Mar 27 2018 · Bauxite is the main source for alumina production With the rapid development of iron and steel industry and aluminum industry highquality iron ore and bauxite resources become increasingly tense However a lot of ironrich bauxite and Bayer red mud resources have not been timely and effectively recycled resulting in serious problems of environmental pollution and wastage of
Figure 2 demonstrated that there was an increase in fluoride removal efficiency with increasing dose of the adsorbent This is due to the increase in surface area and availability of more active sites for adsorption of fluoride Removal of excess fluoride from water by aluminum hydroxide and lateritic soil also revealed similar results when the adsorbent dose increases
A process is disclosed for drying hydrated aluminum fluoride produced from the reaction of hydrated alumina with hydrofluosilicic acid utilizing a turbotray drying system so as to reduce the production of particle fines and recycle thermal energy from upstream operations resulting in an improved and more economical anhydrous aluminum fluoride product
