Summary

  1. 1.

    The method of reverse flotation, based on floculation of magnetite in a magnetic field, with initial magnetite concentrates from magnetic separation being crushed to 30–80% of <0.074 mm size, can yield concentrates with 70–71.8% Fe and high Fe recovery.

     
  2. 2.

    The flotation of nonmagnetic minerals and their concretions with magnetite in a magnetic field can be effected with either cationic or anionic collectors, using relatively small quantities of these, and without the use of depressors.
