Four-Column Flotation Unit | Laboratory & Pilot-Scale Column Flotation by ÜNAL

This video presents the ÜNAL four-column flotation unit, designed for laboratory and pilot-scale mineral processing studies. Web Page Link: https://unaleng.com/products/column-f... The unit integrates four flotation columns of different diameters on a single platform, allowing rapid comparison of operating conditions, scale-up evaluation, and process validation within the same setup. Each column is equipped with independent air flow control and froth washing water adjustment, enabling precise and repeatable flotation testing. Column flotation operates under calm hydrodynamic conditions with low turbulence, which enhances selectivity, especially for fine particle separation. The uniform bubble distribution and controlled froth washing contribute to cleaner concentrates and stable operation. The system includes a dedicated water tank and circulation pump for froth washing, providing consistent wash water delivery to each column. Air and water flow are independently adjustable, supporting flexible test configurations. ÜNAL designs and manufactures this equipment in-house, offering configurable column diameters, connections, and auxiliary components to meet specific research and testing requirements. #frothflotation #columnflotation, #pilotscaleflotation,#flotationmachine #flotationtest #labflotation, #unal
