High-efficiency nanobubble coal flotation
Web1 de ago. de 2013 · Froth flotation is the most widely used method of separating fine coal, especially coal with coking properties. However, froth flotation is not efficient for treating idtrafine coal and coarse coal particles. Our previous fundamental test residts demonstrated that cavitation-generated nanobubbles around 700 tun in diameter can significantly … WebThe compound collector, composed of polar and nonpolar parts, is a current research hotspot in low-rank coal (LRC) flotation because of its outstanding flotation efficiency and cost-effectiveness. However, the selection of compound proportions lacks theoretical guidance. In this study, we comprehensively investigate the internal mechanism …
