    I worked on a porphyry copper ore from Philippines before where I found that dithiophosphate worked better in depressing pyrite in the rougher stage. I experienced a coppergold massive ore type where thionocarbamate seemed to work better. Also, SMBS is a common pyrite depressant. Dithionocarbamates are very selective in copper flotation. It will not float pyrite. Can be used at a .
