ABSTRACT:
A method of separating a mineral component from particulate ore consisting of many components, such as oxides, silicates, carbonates, sulfides etc. is disclosed. The particulate ore is conditioned with a surface-active agent capable of selectively coating one of the components of the ore to the substantial exclusion of coating the other components. A coloring agent having an affinity towards the coating of surface active agent is combined with the surface active agent, providing the coated ore particles with a distinguishable color from the non-coated ore particles. The distinguishable color-coated ore particles are separated from the non-coated ore particles.
