The mined feldspar ore can be manually sorted first, except for the feldspar ore with high concentrate content. The remaining minerals are sent to the crushing stage for coarse and fine crushing operations, and then enter the grinding and classification operation, using rods. The mill and spiral classifier form a closed circuit.Web
