A method is provided of optimizing an ore beneficiation flotation process through which a comminuted ore slurry, which includes a sulphide mineral, passes to produce a final flotation concentrate and a final flotation tail. The method includes measuring the oxygen demand in two or more locations in one or more of the ore slurry, the final flotation concentrate and the final flotation tail, the locations being based on the potential for the oxygen demand in the locations to be significantly different from each other, which would indicate that sulphide mineral particle oxidation can be manipulated. If sulphide mineral particle oxidation can be manipulated, flotation of the sulphide mineral is either promoted or suppressed (activated or deactivated) by manipulation of sulphide mineral particle oxidation depending on whether or not the sulphide mineral includes a valuable metal which it is desired to recover.

L'invention concerne un procédé servant à optimiser l'enrichissement d'un minerai flottant, dans lequel un minerai broyé sous forme de boue liquide contenant un sulfure minéral, produit un concentré flottant final et un résidu flottant final. Ce procédé consiste à mesurer la demande en oxygène dans deux ou plusieurs emplacements du minerai en boue liquide, du concentré flottant final ou du résidu flottant final, ou de la totalité de ces derniers, ces emplacements étant déterminés par la différence importante du potentiel de demande en oxygène, ce qui indiquerait qu'il est possible de manipuler l'oxydation des particules de sulfure minéral. Dans ce cas, le flottement du sulfure minéral est soit favorisé, soit supprimé (activé ou désactivé) par la manipulation de l'oxydation des particules de sulfure minéral en fonction de la teneur ou de l'absence de teneur dans ce sulfure minéral d'un métal précieux.
