Dry beneficiation: This method separates kaolin ore with low water content. Dry beneficiation usually includes coarse crushing, magnetic separation, gravity separation and other steps to remove impurities in ore and improve the selectivity of ore. Adding water during the dry beneficiation process is unnecessary, which can save water resources.Web

The large concentrations of REE were obtained by separating the dense heavy minerals from the coarse fraction (grit) obtained during the typical production of kaolin-group minerals (kaolinite) from kaolin ore. The amount of zircon (estimated from the 6–11 wt.% Zr) and the absence of monazite did not explain the high concentrations of REE in ...Web
