US20030231995A1 Use of ozone to increase the flotation

The use of ozone during certain stages of metal separation by flotation degrades certain collectors that are absorbed on the particle surface, as well as the collectors and frothers in the liquid slurry. As a result, the mineral particle has a fresh surface and new chemical reagents can be added in the subsequent flotation steps. Also since ozone oxidizes the iron sulfide particles faster ...
