as the beneficiation process. Sometime, the beneficiation at the primary level can be done during the mining. Beneficiation needs the characterization of the materials of interest, e.g. (a) Petrographic microscopes, chemical analyses, image analysis, QEMSCAN and electron microprobe systems; and (b) Characterization of the deposits type.
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.

In the quartz sand beneficiation process, the fine-grained fraction with a particle size of less than 0.1 mm is usually called slime. For quartz sand with a large amount of clay and slime, as the particle size becomes finer, the grade of silica gradually decreases, while impurities such as iron and aluminum increase.
