Kaolin ores in Huichang contains these minerals of quartz sand, kaolin, mica and feldspars. In order to recover these valuable resources, some experiments of screening, classification, magnetic separation, grinding and flotation are carried out on the basis of the kaolin ore properties. The test results indicate that quartz sand concentrate can be directly obtained when vibrating screen size used is 10 meshes. Materials that are smaller than the screen hole are injected to hydraulic cyclones which controlling classification size is 325 meshes; kaolin concentrate containing above 33.70% Al2O3 and 0.37% Fe2O3 can be well beneficiated from the overflow through magnetic separation with one stage rougher and cleaner to remove iron. On the other hand, the hydrocyclone spigot flow to grinding and flotation with one stage rougher and two scavengers, mica and feldspars concentrate can be beneficiated in sequence. Therefore, these valuable minerals of kaolin ores can be realized comprehensive utilization. 展开更多
