A process for the separation of minerals of different mineralogical character. The process involves conditioning a milled slurry or flotation concentrate of a mixture of valuable sulphidic minerals and non-sulphidic gangue material with an inert/non-oxidising gas and/or a reducing/deoxifying agent. The conditioning is conducted to achieve a controlled dissolved oxygen content or electrochemical reduction potential conducive to the separation of the valuable sulphidic mineral, non-sulphidic gangue material. The inert/non-oxidising gas and/or reducing/deoxifying agent may be added to the milled slurry or flotation concentrate in a quantity sufficient to increase rejection of the non-sulphidic gangue minerals or to improve the selectivity between the valuable sulphidic minerals and non-sulphidic gangue minerals.
