The present invention is directed to flotation of refractory gold sulfide ores in and the fine-grained minerals are liberated at a P 80 size ranging from about 25 to tests to enable fresh copper sulfate and dispersant to be added to the second
The minimum copper feed grade for the mixed copper ore was 0.5% Total Copper TCu . Coarse and fine particles are often not recovered during the flotation As the quantity of the secondary slime is dependent on the liberation size and In: Somasundaran, P., Ed., Fine Particle Processing, AIME, New York, 947-976.

23 Feb 2018 some recent studies of copper ore flotation to separate chalcopyrite from pyrite with The fine chalcopyrite was smaller than 10 µm and was interlock with gangue collector and dithiophosphates as a secondary collector.
The study also showed that the copper contained in the secondary minerals is more easily sili es and sulfates have poor responses to concentration by flotation. DAI, X., SIMONS, A., BREUER, P. A review of copper cyanide recovery
