Flotation separation of copper–molybdenum sulfides using ...

2015-11-1  1. Introduction. The selective separation of copper–molybdenum sulfide minerals by flotation mostly relies on the use of various depressants. Sodium hydrosulfide, sodium sulfide, cyanide and Noke’s reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite (Bulatovic, 2007, Pearse, 2005, Prasad, 1992, Yin et al., 2010), the main copper ...

Effects of pH and pulp potential on selective separation ...

2021-8-25  Molybdenite (MoS2) is naturally a hydrophobic mineral andis the most important molybdenum source to be usually associated with copper sulfide ore as a trace mineral [1-4]. Because of large differences between the surface properties of molybdenite and other sulfides, molybdenite can be recovered from Cu–Mo ores as a by-product with copper at levels as low as 0.01% Mo. Approximately half of the world's molybdenum production comes from porphyry Cu–Mo ores [5-7]. Since molybdenite is a valuable mineral, high recovery and efficient separation from copper sulfide is very important. Molybdenite floatability is influenced by a number of factors such as particle size and shape, face/edge ratio, degree of crystallization, pH, pulp potential, reagents, etc.. Conventional separation of copper sulfide and molybdenite has been achieved with sulfide bulk flotation followed by selective molybdenite flotation by Na2S/NaSH addition, because Na2S/NaSH acts as a depressant for copper
