Metso Outotec, global supplier for the aggregates, minerals processing and metals refining industries, has patented its new Metso Outotec Concorde Cell technology, which is the first fine and ultra-fine flotation solution for more finely disseminated and complex orebodies which have previously been inaccessible.

This innovation sets a new benchmark in high-intensity pneumatic flotation, reducing plant operation costs and contributing to the sustainability of operations by reducing energy and water consumption per ton of metal produced.

The company’s, vice president, Flotation, Antti Rinne says, “The need to process more finely disseminated and complex ore grades, as well as the declining ore grades and the demand for improved flotation selectivity, all 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.”

The Concorde Cell forced-air Blast Tubes treat 100% of fresh feed combined with tailings recycling to improve performance, allowing finer grind to be liberated without the risk of valuable particles lost to tailings.

“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,” explains Rinne.
