Product Overview Counter-current flotation column combining fine bubble aeration and froth washing for mineral separation and beneficiation, with column diameters available from Φ400 to Φ5500 mm. Key Features Counter-Current Mineralization Opposing movement of descending slurry particles and rising bubbles provides an extended contact zone for particle-bubble interaction. Fine Bubble Aeration Highly dispersed fine bubbles increase the available gas-liquid interfacial area and
