Molecular force plays an important role in the interaction between collector and minerals, which directly reflects the intrinsic reason for the selectivity and collection of the collector to minerals. In this work, the interaction forces between sodium oleate (NaOL) and minerals (kaolinite and diaspore) were directly characterized by atomic force microscopy (AFM) combined with EDLVO theory.

Ilmenite that is weathered and altered loses Fe and becomes less magnetic. A small proportion of the ilmenite must go through electrostatic separation to remove non-conductor mineral contaminants such as monazite, garnet and staurolite from the conductive ilmenite. Non-magnetic minerals go on to a primary electrostatic separation circuit.
