Petrogenesis Of The Az Zabirah South Zone Bauxite Ore
Apr 01, the bauxite ore may be hard or soft, porous or dense, stratified or mottled in texture, and gray, brown, yellow, red, violet or pink in colour. most of the az zabirah bauxite ore deposits occur near the earth’s surface. the south zone bauxite deposits were pisolitic–oolitic with some other colloformic textures related to bauxitization.Apr 11, the separation of the alumina from the impurities in the bauxite ore is usually accomplished by the bayer process. in this process the ground bauxite is leached with caustic soda (naoh) to produce soluble sodium aluminate (naalo2), leaving the impurities in the insoluble residue. the aluminate solution is then decomposed producing al(oh)3 which.
