Foreign matters such as Fe2o3 and Al203 in the original ore mostly exist as wandering grains or attach to the surface and can be removed through measures such as washing and re-selection to enhance the Sio2 content in the ore concentrate. Sand grains have good outer look (approximate to oval shape, smooth surface without edges or corners.
