Pure hematite and chlorite samples were obtained from Anshan city of Liaoning province of China.The pure quartz was purchased from Linqu city of Shandong province of China.The hand-picked ore was carefully crushed，ginned，and then purified by the gravitational beneficiation method.The hematite and quartz were sieved to obtain a certain size fraction（<74μm），and the-10μm size fraction of chlorite was achieved by elutriation.Chemical multi-element analysis（Table 1）verified that the purities of both hematite and quartz were more than 98%，and that of chlorite was above 90%.
