Oct 01, 2020  However, it is known that the available antimony minerals (especially the stibnite) are prone to be oxidized, which results in a massive amount of antimony lost in the flotation tailings. Therefore, recovering the antimony oxide minerals from the flotation tailings is significant for the efficient utilization of resources. Nowadays, flotation tailings containing antimony oxide minerals, with poor
