Abstract
The present application belongs to the field of mineral processing, and particularly relates to a reagent for intensive flotation of complex copper-cobalt oxide ore based on strong inhibition-sulfidation activation-multi-site synergistic collection and application thereof. The present application first adopts the idea of strong inhibition-sulfidation activation-multi-site synergistic collection, uses a closed-circuit flotation process of one roughing, one cleaning and one scavenging, and adds different combined collectors in the roughing, cleaning and scavenging stages, so as to strengthen the collection ability of complex copper-cobalt oxide ore while ensuring the high efficiency of the collectors for copper and cobalt metal, and realize the synchronous improvement of concentrate grade and recovery rate, that is, solve the problem that the collection ability and selectivity are difficult to be considered in the prior art. The reagent component of the present application is reasonably designed, simple and controllable to apply, has excellent flotation effect, and is convenient for industrial application.
