Metso Outotec has launched its Concorde Cell Flotation technology for efficient fine and ultra-fine particle recovery, describing it as a "new benchmark" in high-intensity pneumatic flotation.

The company said the technology would reduce plant operating costs and contribute to sustainability efforts through minimised water consumption per ton of metal produced.

Additionally, it said the Concorde Cell technology is the first fine and ultra-fine flotation solution for more finely disseminated and complex orebodies that have been previously inaccessible.

Antti Rinne, vice president, Flotation at Metso Outotec, said the need to process more finely disseminated and complex ore grades, as well as the declining ore grades and the demand flotation selectively, bring new challenges to minerals processing flowsheets.

"The new Concorde Cell™ technology helps flotation circuits overcome these challenges and recover the previously unachievable ore value," Rinne said.

"Combining the well-proven TankCell® technology with Concorde Cells is a low-risk and high-benefit approach for minerals processing flowsheets.

"The cell produces very high shear and extremely fine bubbles, which increases recovery in particles under 20 microns."
