Color measurements were made for pure minerals, mineral mixtures, and flotation froths loaded with different minerals. The research objective was to correlate colors with the composition of mineral streams. An industrially available system consisting of a fiber- optic-based illuminator and detector was used to measure color. Color values of binary mineral mixtures varied according to the type and proportion of minerals in the mixture. Measured color values of mineralized froths in the laboratory and in a commercial flotation circuit were dependent on the amount and type of minerals present.
