Use of magnetic surfactants in the high gradient magnetic separation of essentially nonmagnetic calcite and barite

Abstract

The minerals calcite and barite are essentially nonmagnetic and cannot be recovered in the magnetic fraction during high gradient magnetic separation. A novel concept of using magnetic surfacant to render the material magnetic has been investigated using manganese stearate and oleate as surfacants. The effect of various parameters has been studied. The technique developed has immense potentiality.
