The physical sorting, gravity separation, flotation, or combination methods are generally used for removing mica from sand depending on the difference between the properties of mica and sand gravel. Due to the particularity of sand and gravel processing, physical sorting is a more reasonable choice. The principle of air-selected mica is simple and the cost is moderate, which is more practical
