Reverse Flotation of Quartz From Magnetite Ore with ...
INTRODUCTION. The reverse flotation is an indispensable process in lowgrade iron ore industry to produce a hematite concentrate. The same method can also be applied to reduce SiO 2 content in magnetite concentrates obtained through lowfield magnetic separation (Xiong 2006 Xiong, D.
