Summary:The authors undertake a critical analysis of zinc flotation activation mechanisms, namely, ion exchange and electrochemical, and propose a new mechanism of activation of sphalerite flotation by heavy metal ions. Flotation can be activated by physisorption of the collector in the unit event of particle–bubble attachment. The causes of floatability of sphalerite activated by lead ions in the alkali range of pH are disclosed. The characteristic of zinc as a metal–activator consists in high solvability of zinc and xanthate compounds. The conditions of improved floatability of sphalerite after its activation by zinc ions are determined.
