目前常用的高岭土加工方法有：浮选法。磁选法、重选法、化学漂白法和氯化还原焙烧法。煤系高岭土因其不同于普通高岭土的组分特征，即有机碳含量高、含铁、钛高，兼顾到加工工艺、技术和成本以及煤系高岭上用作制备优质造纸和陶瓷原料时应尽量保持其片状结构特征等因素，最好?
At present, kaolin processing methods are: flotation method. Magnetic separation method, re-election method, chemical bleaching and reduction of roasting method. Coal-based kaolin because of its different from ordinary kaolin component characteristics, that is, high organic carbon content, iron, titanium, taking into account the processing technology, technology and cost, as well as coal-based kaolin for the preparation of high quality paper and ceramic raw materials should Try to keep its flaky structure and other factors, the best?
