Bauxite ore processing Plant
Sintering process. This method is suitable for treating low grade ores with high silicon content. It requires that the Al2O3/SiO2 is 3～5 (3.5 or so) and the Fe2O3 content is below 10%. In modern industry, the sintering process is alkali-lime sintering process. The bauxite is mixed with certain soda ash and lime (or limestone).
