Taking China Kaolin Company as an example, the production process of kaolin is divided into two parts: mining and beneficiation. Mining process flow: Rock drilling at the mining face → blasting → loading and unloading transportation → lifting → ground transportation → hand selection → kaolinite raw ore.
The large, exposed surface area of the Kaolin enhances the reaction and then the production of Al 2 O 3 increased (Fig. 4).The result revealed that as the grain size increases, the production of Al 2 O 3 decreases where the best size for the optimum condition is 75 µm. Productivity increases as the particle size decreases due to the …
