Abstract
This study investigates the impact of hydrophobic polymers on the wettability and flotation efficiency of key minerals, including chalcopyrite, galena, pyrite, and quartz. Copolymers based on [[2-(methacryloyloxy) ethyl] trimethylammonium chloride] and styrene were synthesized using radiation copolymerization in various ratios. The chemical structures of the copolymers were confirmed through IR spectroscopy, highlighting the key functional groups that contribute to their effectiveness in modifying mineral surfaces. Contact angle measurements were used to assess the changes in wettability of mineral surfaces treated with these hydrophobic polymers. Results showed that the application of the copolymers significantly reduced the contact angles of chalcopyrite, galena, and pyrite, indicating an increase in their surface hydrophobicity. The study also explored the combined use of the polymers with traditional flotation reagents, such as sodium butyl xanthate, demonstrating a synergistic effect that enhanced the flotation process by further reducing contact angles and improving selectivity. The findings suggest that hydrophobic polymers can optimize flotation efficiency by altering the surface properties of minerals, leading to higher recovery rates and improved separation of valuable minerals from waste materials. Additionally, the use of polymers has the potential to reduce the environmental impact of flotation processes by lowering the consumption of toxic reagents.
