The SBM Minerals Flotation Columns are establishing a new standard in flotation technology. For the last two decades, columns have proven their ability to produce higher concentrate grades compared with conventional flotation. However, one of their main drawbacks is a low recovery performance, typically resulting in excessive circulating loads. The sparger is derived from the patented Microcel™ Technology and enhances metallurgical performance by allowing an unprecedented flexibility on the grade-recovery curve. SBM offers industrial expertise and numerous references in full-scale flotation column design, manufacturing, installation, commissioning and training. SBM also supplies testing and consulting services as well as laboratory and pilot units.

Flotation columns are suitable for: Copper, Lead, Zinc, Iron, Graphite, Phosphate, Coal, Fluorspar. etc.

Flotation columns main benefits:
Improved recovery
Optimized grade
Increased throughput
Enhanced bubble particle contact
No plugging
On-line replacement
Reduced wear and maintenance.
A unique sparger technology

Column flotation has gained wide acceptance in the minerals industry as a technically sound and economical means for producing high purity products. Through innovative research and equipment design, EFG has dispelled myths that the application of column flotation is limited to cleaning applications. with over 500 diverse industrial installations, we have demonstrated that CPT columns can be successfully used as roughers and scavengers in both direct and reverse flotation applications.
