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

Our cells are used in roughing, scavenging, cleaning and re-cleaning applications to process copper, zinc, Platinum Group Metals (PGMs), phosphates, graphite, slag and effluents. They feature a stator located on the floor of the tank, a rotor with a provision to introduce flotation air through the center of the shaft, adjustable airflow rates and froth-crowder settings, as well as a launder. Customized launder design options are available in order to ensure specific lip loading and froth carry rates. Other features include internal or external dart valves and precise froth level control instruments resulting in a class-leading combination of process, operational and cost benefits.

MAXGen Mechanism

Our MAXGen mechanism is the result of advanced research, extensive bench scale test work, scale-up and industrial trials. Incorporating the MAXGen mechanism enables an owner/operator to achieve best-in-class metallurgical performance, combined with greater ease of maintenance and lower cost of ownership. The MAXGen mechanism enables the generation of a swarm of air bubbles with optimum size distribution. A careful selection of a trade-off between the agitation levels and the bubble distribution facilitates the flotation of fine and coarse particles equally, whilst efficiently keeping solids in suspension, which in turn maximizes the probability of bubble-particle interaction.

Main advantages of our DELKOR BQR flotation cells

  • Improved metallurgical performance
  • Precise froth level controls
  • Low downtime and increased ease of maintenance
  • Internal or external dart valves with a strong focus on safety
  • Cell bypass ready provision for larger cells to facilitate quick, easy and safe cell maintenance
  • Cell bypass improves circuit flexibility to a great extent
  • Enhanced power efficiency
  • Low maintenance cost and total cost of ownership

Our DELKOR BQR flotation cells range in size from 1.5 m³ (BQR15) to 300 m³ (BQR3000) and our MAXGen mechanism now maximizes bubble-particle interaction for improved flotation kinetics.

    Fabrication, supply and installation of three cells in Utah

    Three 40m³ BQR 400 flotation cells were supplied for CML Metals Corporation’s Iron Mountain Project. The flotation cells were manufactured in the USA to accelerate delivery. 

    The reverse flotation circuit process forms part of a two stage magnetic separator circuit. The non-magnetics, silicates and apatite, are removed as floated product, and pumped to a 20 m diameter DELKOR tailings thickener. The magnetics are pumped to a 16 m diameter Delkor concentrate thickener.

  • Value for Money
