Title: Method for separating electrically conductive mineral components from electrically non-conductive mineral components of an ore

Abstract: An improved method for separating electrically conductive components of an ore or mineral sand from electrically non-conductive components of the ore or mineral sand is disclosed which includes processing the ore, adding a polymer, such as an anionic polymer, to the processed ore, drying the polymer and ore, and then feeding the ore and polymer through an electrostatic separator. The addition of the anionic polymer to the processed ore increases the efficiency of the electrostatic separation process.
