A process for separating ore particles from gangue particles comprises the steps of (1) conditioning the particles with an agent comprising a compound having both a surface-selective functional group and a detectable moiety, to selectively coat either the ore particles or the gangue particles, to the substantial exclusion of the other; (2) detecting the coated particles; and (3) separating the detected, coated particles from the substantially uncoated particles. In one embodiment, the detectable moiety is fluorescent and detecting is performed under ultraviolet radiation. |
