The first Outotec TankCell e500 to be delivered to First Quantum Minerals

Gerald Ondrey

To address the market demand of increased capacity and volume Outotec Oyj (Espoo, Finland; has developed the mega-size flotation cell based on its well-established technologies. The first TankCell e500 flotation cell will be installed to First Quantum Minerals' Kevitsa operation in Finland. It is one of the world's largest flotation cells with an effective volume of over 500 m3.

First Quantum Minerals' Kevitsa operation, commissioned in 2012, is a nickel-copper-platinum group elements (PGE) mine located north-northeast of Rovaniemi in the Finnish Lapland.

"The TankCell e500 will provide significant additional capacity and flexibility to the Kevitsa flotation flowsheet without taking up significant real estate. The net result is efficient use of capex (capital expenses) and, going forward, opex (operating expenses),” says Anthony Mukutuma, plant manager at FQM Kevitsa Mining Oy.

Outotec previously delivered grinding mills, filters, thickeners, an automation package and flotation cells to Kevitsa during the project construction. The flotation circuits have in total 68 Outotec TankCells of which 14 are large 300 m3 machines. The new TankCell e500 has been manufactured and preassembled in a workshop in Finland and passed all mechanical and fluid dynamical performance tests.

"Outotec is renowned for the performance, innovation and efficiency of its flotation technology. This contract further strengthens our position as the global technology leader in flotation. With over 400 sold TankCell e300 flotation machines Outotec is also a clear market leader in the large size range. The new 500 m3 cell is Outotec's response to growing throughputs, low ore grades, and need for lower capital investments and production costs", says Kalle Härkki, president of Outotec's Minerals Processing business area.
