采用新的和先进的加工技术可以获得高纯粘土矿物。尤其对高岭土和蒙脱石一类矿物更是如此。这种加工技术为湿法工艺,包括分级、强磁选、化学漂白、浮选和选择性絮疑。高纯粘土矿物与其它矿物混合使用,可制成特殊陶瓷材料,如堇青石与其它矿物。这类矿物都具有特殊的陶瓷性能,如热膨胀低。耐火强度高、吸附性低等其它所期望的性能。 High-purity clay minerals can be obtained using new and advanced processing techniques. This is especially true of minerals such as kaolin and montmorillonite. This processing technology for the wet process, including grading, strong magnetic separation, chemical bleaching, flotation and selective scouring. High purity clay minerals mixed with other minerals can be made into special ceramic materials, such as cordierite and other minerals. These minerals have special ceramic properties, such as low thermal expansion. High fire resistance, low adsorption, and other desirable properties.
