Flotation and Purification Research on Low Grade

Low grade magnesite coexisting with dolomite was purified by flotation. A process of reverse flotation to remove silicate minerals- positive flotation to concentrate magnesite was explored after the systematic process mineralogical investigation. Influence of different conditions such as grinding fineness experiment, collector experiment and combined modifiers experiment was also investigated.
