Kaolin is an important non-metallic mineral resource with good application properties such as adsorption, plasticity and stability. It is widely used for material preparation fields such as papermaking, ceramics, rubber, refractory material and so on. However the quality of kaolin produced in China is relatively low. High-quality kaolin usually relies on imports.
The experimental study on mineral processing of kaolinite accompanied by quartz in Guangdong was carried out in order to obtain quartz sand products meeting the requirements. The tailings were obtained after the kaolin raw ore was mashed and graded to separate the −0.045 mm particle size kaolin product. The +0.1 mm grain size material accounting for …
