Able to produce high-grade concentrates to meet final product specifications, our column flotation cells are ideal in cleaner applications, complementing mechanical cells and improving overall flotation performance. They are also effective for reverse flotation of insoluble silicas from iron ores.
The column cell’s large height-to-diameter ratio ensures a large collection zone with ample space for target mineral-bubble attachment. Collision and attachment rates are further enhanced by the venturi-style inline sparging systems, which delivers much higher intensity contacting that traditional jet-nozzle spargers.
A large collection zone allows the column to operate at much deeper froth depths than traditional mechanical flotation cells for effective washing and cleaning of the concentrate before recovery. But it’s the use of wash water that really permits high upgrading, facilitating the washing clean of floating froth and overflow of high-grade concentrate into the concentrate launders.
The sparging system on FLS column flotation cells – including recirculation pump and spargers – is externally mounted, simplifying maintenance by eliminating the need to enter the tank. Optional sparger isolation valves allow the spargers to be serviced online.
FLS column flotation cells feature a modular construction, with components readily containerised for delivery to site. This minimises engineering costs, simplifies logistics, cuts delivery times, and reduces onsite fabrication times, costs, and safety risks.
The experts at the FLS Minerals Testing and Research Centre help fine tune your flotation systems to ensure optimal performance. Equipped with a range of testing and analysis equipment, we determine the optimal sizing, configuration, and operating practices of your flotation circuit. Operating flotation cells are supported by a global network of service centres, offering full-lifecycle technical assistance. Our service engineers travel regularly to sites for equipment inspections and audits, to supervise maintenance, and to deliver tailored training. Meanwhile, FLS spare and wear parts deliver long service life and ensure the performance of your flotation cells does not degrade over time.
