Optimisation of gold recovery by selective gold flotation
1/2/2001#0183;#32;Modifiers pH modifiers The operating pH for the flotation of gold is dependent on the collector. In a study by Klirnpel and Isherwood (1993), the collector S701 exhibits its highest gold recovery from a goldpyrite ore at a pH of while F100 performs at its best with the same ore at a pH greater than 12.
