Review of the flotation of molybdenite. Part I: Surface properties …
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 (Bulatovic, 2007, Guang-yi et al., 2012).
