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.
