2014-4-1  In modern gold beneficiation, electrostatic separation via triboelectricity has been tested but has no practical use (Inculet et al., 1988). However, static electricity is an essential secondary effect in the winnowing or “dry washing” of gold ( Wilson, 1961 ); a dry washer separates gold from sand using an air pulse through a porous blanket of wool or other fiber that has insulating properties.
