WebParticle collection by air bubbles is regarded as the heart of froth flotation operation. Then, nanobubbles, which refer to tiny bubbles mostly finer than a few hundred nanometers, can extend the lower particle size limits for effective flotation of coal, phosphate, iron ore, some typical oxidized minerals, etc. WebCAVITATION NANOBUBBLE ENHANCED FLOTATION PROCESS FOR MORE EFFICIENT COAL RECOVERY Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range, e.g., between 50 µm and 600 µm for coal and between 10 µm and 100 µm for minerals.
