Climax recovers a heavy mineral concentrate by passing the rougher tailings from molybdenite flotation over Humphrey spirals. This concentrate is floated using xanthate at pH 4 to remove sulfides, principally pyrite. The tails from the pyrite float are then cleaned of quartz, feldspar and light minerals by tabling. Amine flotation follows at pH 1.5 and 75°C to float monazite.

Tungsten is found mainly in the minerals wolframite (iron–manganese tungstate (Fe,Mn)WO 4, which is a solid solution of the two minerals ferberite FeWO 4, and hübnerite MnWO 4) and scheelite (calcium tungstate (CaWO 4). Other tungsten minerals range in their level of abundance from moderate to very rare, and have almost no economical value.
