Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ). Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 ).
