Abstract

Email to a Friend
The mechanism of activation of ZnS by metal ions and the subsequent flotation induced by xanthate has been considered as a surface redox reaction. By ultraviolet (UV) irradiation of ZnS suspensions, the normally inert ZnS is caused to react with xanthate in the absence of activator. By similar UV irradiation, the rate of adsorption-exchange of activator ions at the ZnS-H2O interface is also increased. Mechanisms of these reactions are proposed and compared to current electrochemical and semiconducting models of sulfide flotation.
