With a legacy of innovation and a focus on performance, the DELKOR BQR Flotation Cell is the result of extensive research and development, including advanced Computational Fluid Dynamics (CFD) modeling, rigorous laboratory testing and successful full-scale installations worldwide. The core of this success lies in the MAXGen mechanism, which has revolutionized flotation by optimizing bubble-particle interaction and delivering faster flotation kinetics, leading to superior metallurgical performance.
“MAXGen is more than just an upgrade – it’s a game-changer,” explains Shiraz Hussain, Senior Project Engineer at TAKRAF South Africa. “Its performance has been validated across several global installations, including major operations in South Africa and India. The technology enables increased recovery rates, reduced energy consumption and more flexible, maintainable flotation circuits.”
Performance-driven design
The MAXGen mechanism enables the rotor to operate at a lower tip speed, significantly lowering power consumption and wear while improving the energy profile of the flotation process. This not only reduces operational expenditure (OPEX) but also supports long-term sustainability goals. The optimized hydrodynamics enhance bubble size distribution, which directly improves mineral recovery.
The design’s cell bypass provision and froth level control features offer operational flexibility and minimize downtime – both critical in environments where efficiency equals profitability. Additionally, maintenance-friendly components and robust construction ensure equipment longevity and reliability under toughest conditions.
Proven success in Africa
The demand for DELKOR BQR Flotation Cells across the African continent is rising. A recent platinum project in South Africa marked TAKRAF Group’s largest flotation cells installation in Africa by surface area, with 14 cells deployed – each featuring the MAXGen mechanism. This followed a successful four-cell installation for a magnetite operation in the Northern Cape.
“These projects demonstrate how African mining operators are embracing technology to meet production targets and stay competitive,” says Hussain. “We’re also seeing increasing interest from brownfield operations aiming to debottleneck existing plants or boost capacity with modern equipment.”
TAKRAF Group is currently supporting multiple African clients in optimizing their gold and base metal operations with DELKOR’s flotation and thickener technologies. These solutions not only enhance performance but also contribute to sustainable mineral processing practices.
A global technology with local Impact
Beyond Africa, the MAXGen-equipped cells have been installed in diverse geographies – from fluorspar processing in Spain and iron ore in Honduras to gold and nickel operations in Australia. Each project demonstrates the flexibility and customization that DELKOR offers to meet unique site requirements and commodity-specific challenges.
“Whether it’s UV-resistant coatings for harsh climates or custom froth discharge boxes, our team ensures each solution is tailored for maximum client value,” notes DELKOR India Managing Director Rajiv Krishnamurthy.
TAKRAF Group’s comprehensive support services – from design and engineering to commissioning and aftermarket care – reinforce its reputation as a reliable partner in minerals processing.
Looking ahead
As African mining continues to evolve, embracing advanced technologies like DELKOR BQR Flotation Cells with MAXGen mechanism will be key to unlocking greater value from every ton of ore processed.
