separator could also be used to enhance these effects. Some equipment manufacturers market pure triboelectric separators, such as Outotec's T-Stat separator. Where minerals have very similar conductivities but significant triboelectric differences, such separators may be more effective than the combination of inductive and triboelectric effects.
