DELKOR BQR FLOTATION CELLS
DELKOR’s new generation BQR flotation cells, equipped with the proprietary MAXGen mechanism, achieve
best-in-class metallurgical performance with a view to maximizing the sustainable recovery of minerals.
best-in-class metallurgical performance with a view to maximizing the sustainable recovery of minerals.
The MAXGen mechanism is the culmination of state-of-the-art research, extensive bench scale test work, scale-up
and industrial trials.
and industrial trials.
Incorporation of the MAXGen mechanism within a BQR flotation cell makes it possible to achieve best-inclass metallurgical performance, combined with greater ease of maintenance and lower cost of ownership.
The MAXGen mechanism focuses on the generation of a swarm of air bubbles with optimum size distribution, which facilitates the flotation of fine and coarse particles equally, while keeping the solids in suspension efficiently. This maximizes the probability of bubble-particle interaction.
