It is known that up to 25%–30% of Mo, Cu and Re goes to rough flotation tailings and is lost in wastes. Those losses are a consequence of the ore composition variability, chalcopyrite–molybdenite ratio, an increase in the proportion between primary copper sulfide and finely disseminated molybdenite and the recovery of floating pyrite.

What is a Primary Crusher?
A primary crusher breaks up large pieces of rock or concrete from the blasting or excavation process and turns them into smaller, more manageable chunks. This is the first step in the crushing process. The smaller pieces can then either be pre-screened or fed directly into a secondary impact or cone crusher.

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).
