· If the feldspar ore is soft, easy crushing, put them into the grinding mill machine to peel off the iron material in the mica group minerals. The result shows that the stripping-strong magnetic separation process has a significant improvement, besides, its cost is lower than that of the magnetic – flotation combined flow.
