The TankCell e630 is the latest addition to Outotec’s flotation portfolio, which already offers a wide range of cell sizes. With an effective volume of 630 m3 as standard, and volumes of close to 700 m3 achievable depending on the chosen configuration, it is the largest flotation cell in the world, according to Outotec.

Suitable for all flotation applications, the e630 is designed to meet the market demand for increased capacity combined with improved production and energy efficiency. It incorporates innovations such as the Outotec FloatForce mixing technology, which empowers pumping performance, as well as better air dispersion and mixing capability, improved efficiency and longer component wear life.

The TankCell e630 outperforms smaller cells in terms of energy efficiency while enabling a significant increase in production capacity. Compared to an equivalent plant build using the smaller Outotec TankCell e300, total capital cost can be reduced by as much as 10% to 20%. Typical installed power for the e630 is 500 kW/600 hp and specific power consumption is lower than that of smaller TankCells.

Outotec recommends using a variable frequency drive to enable optimization of both metallurgy and power consumption in these high-capacity production units. Its large capacity makes the Outotec TankCell e630 particularly suitable for rougher and scavenger duties in gold and base metal applications. The unit has a diameter of 11 m and a lip height of approximately 7 m.
