Advanced flotation solutions with DELKOR BQR Flotation Cells

Our new generation DELKOR BQR Flotation Cells, equipped with our latest MAXGen™ mechanism, achieve superior metallurgical performance and assist in maximizing metal recovery, while also providing for ease of maintenance and lower cost of ownership. 

DELKOR BQR Flotation Cells achieve optimum operation, through improved particle-bubble interaction, faster flotation kinetics and precise froth level controls.

Our flotation cells are used at various processing stages, namely for roughing, scavenging, cleaning and re-cleaning, and are suitable for processing copper, zinc, platinum group metals (PGMs), phosphates, graphite, ferrous minerals and effluents. 

Customized launder design options are available to ensure specific lip loading and froth carry rates, including peripheral, radial or combination of peripheral and radial launders. Also explore DELKOR’s Belt Linear Screens or APIC Jigs.

MAXGen™ Technology

Our MAXGen™ mechanism is the result of advanced research, extensive bench scale test work, scale-up and industrial trials. MAXGen™ enables the generation of a swarm of air bubbles with optimum size distribution. A careful trade-off between agitation levels and bubble distribution facilitates the flotation of fine and coarse particles equally (especially relevant for the flotation of low-density minerals), while efficiently keeping solids in suspension. This in turn maximizes the probability of bubble-particle interaction.

Benefits

Improved metallurgical performance

  • Optimum bubble size distribution suitable for fine and coarse particle flotation
  • New improved rotor and stator combination for better mixing/agitation in cell
  • Faster flotation kinetics from better mixing and finer bubbles means faster mass pull to froth
  • Customization of froth crowder size and launder type for optimised combination of froth area, lip length and froth carrying rate, to attain desired grade-recovery curve in section of flotation circuit

Precise froth level controls

  • Option of internal and external dart valves for precise control of slurry level/froth height, ensuring consistent froth overflow velocity to launders and improved mineral grade recovered to the froth
  • Back pressure pipe installation at last cell reduces pressure drop and provides improved level control and mass pull

Less downtime and increased ease of maintenance

  • Easy access manhole at tank bottom, through which internals easily removed out of cell
  • Stator in multiple segments for larger cells
  • Froth crowder in multiple segments
  • Walkways of modular design offer flexible access layout
  • Cell bypass facilitates quick, easy and safe cell maintenance

Low maintenance cost and total cost of ownership

  • Optional bolted tank design for easier transportation and quicker erection time
  • Optional local manufacturing of tanks, either in welded or bolted design, to reduce logistics cost and time
  • Lower tip speed of MAXGen rotor reduces power consumption

  • Reduced wear rate of rotor and stator
