Flotation Collectors - 911 Metallurgist

Aug 10, 2015  Typical sulfide collector dosages range from 0.01 to 0.1 kg/ton of dry feed to flotation, with some applications ranging up to 0.5 kg/ton. Specifically, the uptake of xanthate by a given sulfide mineral has been shown in idealized laboratory tests to depend on the rest potential of that mineral.
