Enhancing Fines Recovery by Hybrid Flotation Column and Mixed Collectors

The froth flotation technique can be considered one of the most efficient methods for separation minerals. Prior to utilizing any physicochemical method, size mined ore must decreased facilitate release valuable materials. This practice, along with increased exploitation ores that carry fine mineral particles caused production and ultrafine which are difficult recover classical enrichment methods, due their different characteristics compared coarser particles. It is established float, leading losses minerals, mainly low collision efficiency bubbles. Moreover, require higher reagent consumption fact have a specific area, finally, limited by kinetic energy. Flotation fines enhanced either decreasing bubble diameter or increasing apparent size, moreover, enhancing collector’s adsorption (their hydrophobic behavior) using alternative reagents (non-ionic co-collectors). In present research, experiments on hybrid electrolytic column produce microbubbles (−50 μm), were carried out recovering magnesite (−25 μm) addition, synergistic effect anionic/non-ionic collectors studied enhancement recovery. Experimental results so far designate particle recovery approximately 8% addition microbubbles. Finally, anionic/non-anionic led improvement almost 12%.
