    Magnetic- reverse flotation separation is to collect hematite from hematite ore in the way of magnetic separation first, and then use reverse flotation to separate the rest of minerals in neutral pulp (the pulp pH is 7) with dodecylamine cations as the collector. In this way, the quality of iron concentrate can effectively be improved.
