Bayer method is currently used in 95% of alumina production in the world, which requires higher bauxite grade. [2,3,4,5,6] If the ore with Al/Si ratio less than 7 is treated simply by Bayer method, the low-grade high-silica bauxite must be desilicated by roasting-alkali leaching pre-processing method prior to be used in the Bayer system.
metallurgical alumina produced from bauxite still dominates the world's alumina production due to the technical and economic feasibility of the Bayer process. A high-grade bauxite, with a mass ratio of Al 2 O 3 to SiO 2 greater than 6.25 [1, 2], and/or high Al 2 O 3 to Fe 2 O 3 ratio [3], can be
The removal of phosphorus impurities is among the most important problems in the purification of upgraded metallurgical-grade silicon (UMG-Si) used in the preparation of solar-grade silicon (SOG-Si).
