Some mines in Liaoning, China tested with a multi-stage grinding-multi-stage separation process, with the obtained concentrate contained 63.29% iron, with 69.42% recovery, when the final grinding fineness is −0.074 mm at 99.38% [11]. The latter process, although simple and short, still ...
The magnetite and quartz samples used in this study were obtained from mines in Yunnan, China. The original ore sample was crushed into 2 mm particles and impure sample impurities were thrown away by hand under an optical microscope. The X-ray diffraction pattern of the pure sample is shown ...
