Optimised Mineral Recovery

ENPROTEC’s Flotation Technologies are utilised to deliver advanced mineral processing solutions designed to maximise recovery, improve efficiency, and reduce operational costs. Our range of flotation technologies (KinetiCore™, Dual™, Dual Circuit™, MaxFloat™, PneuPure™ and FlashPro™) is engineered to excel across diverse processing requirements for various ore types and plant conditions. Our technologies combine innovative design with robust engineering to ensure superior metallurgical performance and long-term reliability.

By optimising particle-bubble interaction, froth stability, and circuit flexibility, ENPROTEC’s flotation solutions enable higher yields, improved grade control, and reduced energy and reagent consumption. This results in a more efficient, sustainable process that lowers maintenance demands while increasing plant throughput. Whether for fine- or coarse-particle recovery, complex circuits, or ultra-fine applications, ENPROTEC provides tailored solutions that enhance productivity and profitability.

Integrated Reaction Chamber – Localised Energy Input

Our confined, adjustable mechanically agitated reaction chamber forces feed slurry, air and reagents together, resulting in above average energy input, ensuring maximised bubble/particle interaction for efficient flotation kinetics. Additionally, due to the unique efficient energy input, the Dual Cell™ is capable of beneficiating ultra-fine (-25 micron) particles resulting in higher recovery rates in comparison to conventional flotation technology.

Ultra-Fine Bubble Generation

This high-shearing, mechanical energy input results in ultra-fine bubble generation, resulting in up to 5 times the carrying capacity of conventional flotation technology.

Technically Engineered

Air Dispersion and Bubble Generation

Effective air dispersion and bubble generation are critical for maximising the flotation cell’s performance. At ENPROTEC, we utilise advanced impeller and diffuser designs that ensure uniform air distribution and ultra-fine bubble creation. This increases the surface area for particle attachment, enhancing the recovery of valuable minerals. The use of high-efficiency air supply systems and precise air control mechanisms further optimises the flotation process, improving separation efficiency and throughput.

Cell Design and Material

The design and material-of-construction of flotation cells impact their durability and efficiency. ENPROTEC employs robust construction materials such as stainless steel and specialised composites that resist corrosion and wear, extending the lifespan of the equipment. Our cell designs, including tank geometry and reaction chamber engineering, are optimised to promote effective mixing and prevent/eliminate short-circuiting, ensuring consistent performance and high recovery rates.

Automation and Control Systems

ENPROTEC flotation technologies are equipped with advanced automation and control systems. These systems utilises PLC, advanced control systems and live analytics to automate and optimise the flotation process, including reagent addition, airflow control, and froth depth management. Real-time monitoring of parameters such as energy input, pH, Eh, and froth depth allows for dynamic adjustments, optimising recovery and grade across a full particle size distribution spectrum. Features like remote monitoring and data logging provide valuable insights for continuous improvement.

Froth Management and Collection

Efficient froth management is essential for maximising recovery and product quality. ENPROTEC’s flotation cells incorporate innovative radial and circumferential froth launders that effectively direct froth to the overflow weirs, minimising froth travel distance, retention time and promoting rapid collection. Adjustable froth washing systems remove entrained gangue particles, improving concentrate grade. Additional options, such as the integration of froth cameras and level sensors, ensure precise control over the froth layer, enhancing operational stability and performance.
