TAKRAF says its MAXGen flotation technology was developed by careful selection of a trade-off between the agitation levels and the bubble distribution to facilitate flotation of fine and coarse particles equally, efficiently keeping solids in suspension which, in turn, maximizes the probability of bubble-particle interaction.

Maximizing the sustainable recovery of minerals has become a critical success factor at a time when the efficient recovery from less rich ores, aging or secondary deposits is one of the mining industry’s key challenges. TAKRAF Group, known for its Delkor brand of liquid/solid separation and beneficiation equipment, recently introduced new-generation BQR flotation cells with the proprietary MAXGen mechanism, claimed to provide best-in-class performance.

TAKRAF said the MAXGen mechanism — a product of extensive bench scale tests, 3D prototyping, pilot scale studies and plant scale trials — offers superior recoveries with higher mineral grade, along with faster flotation kinetics by generating favorable bubble size distribution and energy-efficient hydrodynamics. A unique rotor/stator configuration enables the rotor to operate at a lower tip speed, providing reduced power consumption and wear.

According to the company, the MAXGen flotation cell also offers additional features that address practical concerns related to installation, maintenance and operation of flotation circuits, particularly in existing concentrators. For example, its “bypass-ready tank design” allows for installation and upgrading with cell bypass systems at any stage, without compromising the original layout and without modification to the tank shell. This flexibility makes adjustments faster and cheaper, enabling operators to continually optimize flotation bank setup over time.

The new flotation cell incorporates deeper launders with higher slope to help evacuate froth quickly. Cells can also be customized with various optional external, internal and radial launders to suit specific froth transport parameters based on the application.
