In general, the iron recovery was superior when magnetic particles were introduced, regardless of the addition of bare magnetic or functionalized iron particles. When iron-crosslinked-dextran particles were added into the pulp at the dosages of 0.5 and 1.0 g/t, an increase in recovery of about 7% took place at 0.34 T, but with a loss in grade ...

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
