Column Flotation 4-Columns
Product Overview
The 4-Column Flotation Machine is a multi-column column flotation test unit designed for laboratory and pilot scale studies, allowing direct comparison of different column diameters on a single platform. Integrating four columns into one system makes it possible to evaluate scale effects more clearly under the same feed and operating conditions, supporting meaningful process optimization and scale-up validation.
Compared to mechanical flotation cells, column flotation typically operates under a lower-turbulence hydrodynamic regime. This calmer environment can improve selectivity, especially for fine particles, and supports the formation of a cleaner and more stable froth zone. With multi-column configuration, changes in bubble structure, froth behavior, and recovery trends can be observed as the column diameter increases, enabling side-by-side evaluation in a controlled setup.
Precise Air Control and Froth Washing
Each column includes independent air flow adjustment, allowing fine control of bubble generation and gas rate per column. The system is also equipped with adjustable fan-type froth wash nozzles mounted at the top of the columns. Froth washing helps reduce entrainment of gangue minerals into the froth, contributing to improved concentrate quality.
Column Dimensions :
- Column 1: 50 750 mm
- Column 2: 75 850 mm
- Column 3: 100 1000 mm
- Column 4: 150 1500 mm
These diameter and height combinations allow comparative column flotation testing and pilot scale verification within a single integrated system.
