Metso celebrates flotation milestone, new headquarters

September has been a busy month for Metso with the company marking 50 years in mechanical flotation as well as moving its headquarters to Matinkylä, Espoo, Finland from Sanomatalo, Helsinki. 

Evolving from humble beginnings at Outokumpu, and then further developed by Outotec, Metso has shaped the course of mechanical flotation and propelled the industry forward. The OK cell was taken into commercial use in 1973 with a capacity of 16 cubic meters. In 1995, the company launched the TankCell as the industry shifted to round-shaped tanks.

“TankCell is a great example of our history in flotation,” said Antti Rinne, VP, Flotation at Metso. “Everybody who talks of TankCell flotation cells is speaking of our technology. We remain the original and leading provider of TankCell technology.”

In 2021, the Metso Concorde Cell, which is capable of recovering unachievable fine and ultra-fine particles, entered the market. The patented technology – the first of its kind – is tailored for finely disseminated and complex orebodies that were once considered inaccessible.

Furthermore, today’s flotation circuits are often designed and optimized with Metso’s HSC simulation tool, noted the company, thus enabling optimization of total flotation cell volume and other key flotation parameters.
