The new Metso Outotec ColumnCell leverages the company’s legacy technologies, as well as state-of-the-art best practices, delivering superior metallurgical flotation performance and energy efficiency for a wide range of applications and duties.

“In designing the new ColumnCell, current and future customer needs were carefully studied,” said Antti Rinne, Flotation Vice President at Metso Outotec. “Optimized grade is especially important in cleaner circuits and can lead to significantly higher throughput for the entire flotation circuit. Flotation of fines requires specific features: high collection with smaller bubbles to guarantee good recovery, a less turbulent regime and good slurry distribution to avoid bypass, as well as a thicker and more selective froth to generate better product quality. We have designed ColumnCell to provide all these features, while also taking into consideration the ore type and the specifics of each project.”

For optimized performance of column flotation, Metso Outotec offers three sparger technologies: Microcel Static mixer, SonicSparger Vent and SonicSparger Jet. All three sparger options can be replaced online to maximize equipment availability and production rate and to reduce energy consumption due to fewer shutdowns and startups.

With the introduction of the new ColumnCell, Microcel flotation cell sales will be discontinued.

Over the years, Metso Outotec has delivered almost 300 flotation columns worldwide.
