Reverse Flotation For Magnetite

Aug 01 2019 in this work fine magnetite was used as a magnetic seed to enhance the separation efficiency of fine hematite from quartz during reverse microflotation gradual increases in hematite recovery and iron grade were accomplished with increasing magnetite content whereas the iron content in quartz reject decreased.
