Formally a Bateman product the BQR Flotation Cell has been merged with the traditional Delkor products and renamed the Delkor BQR Flotation Cell.
This range of round tank flotation cells achieve optimum operation through purpose-designed levels of solidssuspension, air rate adjustment, easy froth-cone positioning and a stable pulp-froth interface.
The cells are used in roughing, scavenging, cleaning and re-cleaning, unit and pilot cell applications to process copper, zinc, platinum group metals, phosphates, graphite slag and effluents.
The number of cells required depends on the application. Cells feature an overhung stator, open inlet to the rotor, adjustable air flow rates and froth-cone settings and a launder external to the pulp zone to yield an excellent combination of process, operational and cost benefits.
Process advantages
• High shear forces for better bubble-particle contact
• Good balance between grade and recovery achieved through appropriate rotor and stator selection
• The bubble surface area flux is easily optimised by
selecting the correct blower-rotor-stator combination
• Easy process
optimisation through air supply and froth cone adjustments
• Efficient air distribution.
Operational advantages
• Easy startup under load
• Ideal froth conditions are maintained
• Robust instrumentation achieves stable operation
• Quiescent pulp-froth interface
• Low downtime and easy maintenance
• Spares readily available
• Complete mechanism removable for workshop maintenance
Cost benefits
• Simple design reduces the cost of spares
• Enhanced power efficiency
• Low maintenance cost.
The BQR flotation cells range in size from 0.5m³ (BQR5) to 150m³ (BQR1500).
