Why to consider flotation cell replacement?

Aging, underperforming flotation equipment can have a huge impact on a plant's metallurgical performance, energy efficiency, and ultimately, its profitability. This can cause challenges in meeting operational targets due to low concentrate output from cells, while equipment breakdowns have a negative impact on availability and high spare parts costs affect operational profitability.

Older plants are typically equipped with a large number of cells with relatively small volumes, meaning that metallurgical performance is far from optimal. Furthermore, operations need flexibility over time due to the variation in head grades, and this could require changes in both the capacity and flotation duty of some cells.

Our flotation cell replacement can solve these challenges. The redesigned circuit will deliver optimized cell volume and size, froth carry rate, and residence time. Outotec TankCell units offer superior flotation performance and are designed to maximize the customer's return on investment, with low lifetime operating costs, low maintenance requirements, and high reliability.

New tool helps estimate the value of flotation cell replacement

Feasibility evaluation of flotation circuit modernization has become a lot easier now thanks to a new value calculator developed by us. The tool provides a fast and effective way to evaluate how much operating costs can decrease and what are the monetary values of gained process improvements by replacing aging flotation cells with Outotec TankCell® technology.

For example, if your flotation circuit consists of 30 16m3 cells, those could be replaced with 4 130m3 Outotec TankCells.

Based on the given parameters and case specific values for electricity, slurry and other variables, the tool not only recommends the solution but also calculates the savings for the new flotation circuit solution. The calculator also shows how flotation cell replacement affects CO2 emissions. In other words, the tool provides a quick estimate for achieving a more efficient flotation circuit. This value gains can then be further explored based on more detailed variables and site specific considerations with an expert from Outotec.
