Abstract

Language:

Clays are prevalent in ore bodies and can cause significant challenges in various mineral processing operations, including comminution, flotation, leaching, thickening, and tailings disposal. This study investigates the interactions between different clay minerals and polyelectrolytes often utilized as dispersants. Methodologically, it involved analyzing the electrostatic interactions that can lead to increased association between clay particles and the extent of this association, which is influenced by adding ions or dispersants. Results indicate that such interactions can modify the surface potential of clay particles, reducing their tendency to associate. Furthermore, the research highlights the impact of ultra-fine and fine clay fractions on pulp viscosity, which notably hinders further processing. Additionally, clay's presence in flotation processes is shown to negatively influence mineral recovery by facilitating the attachment of hydrophilic gangue materials to valuable hydrophobic minerals. In summary, the effective application of dispersants that inhibit these associations can enhance recovery rates in flotation circuits. This comprehensive analysis underscores the importance of understanding clay-mineral interactions in optimizing mineral processing operations.
