Since bauxite contains impurities such as ferric oxide, silicon dioxide, titanium dioxide, potassium oxide, and sodium oxide in addition to main components such as aluminum oxide, it is necessary to purify and remove slag from the bauxite before processing. At present, the method for purifying bauxite is to mix bauxite, grinding aid aluminum chloride, dispersant sodium hexametaphosphate and water to obtain slurry, and then purify it through a slag removal device to obtain the finished product.
