As mentioned, valuable sulfide minerals such as chalcopyrite are commonly intergrown with gangue minerals such as talc [ 1, 2 ]. This is generally the challenge in the selective flotation of such minerals. In other words, the talc separation from other valuable sulfide minerals can be difficult since talc has good natural floatability.
