The hematite separation process mainly involves various methods to extract valuable minerals from the ore, including crushing, grinding, magnetic separation and flotation. It is suitable for processing hematite with complex structure such as hematite and impurities with uneven particle size distribution, ores with more fine particles, ores with ...
