With the increased demand for metals, miners are evaluating their mineral processing flowsheets, with the aim of optimising their performance.
At the same time, both greenfield and brownfield projects are considering processing new complex ore types which can be finely disseminated, requiring fine particle grinding to achieve metallurgical targets. Optimal flotation performance occurs within specific size ranges, typically between 25 – 150 µm, depending on the application. Particles smaller than 25 µm are considered to be fine or ultra-fine particles. These particles have distinct characteristics that require specific flotation conditions for effective recovery.The Concorde Cell™ flotation technology by Metso is designed to efficiently recover fine and ultra-fine particles and the previously unachievable ore value. The Concorde Cell technology is the first fine and ultra-fine flotation solution for more finely disseminated, complex, and previously inaccessible ore types within various minerals processing flowsheets (e.g. gold, copper, nickel, platinum, silver, lead, zinc, and molybdenum).Revolutionising flotation efficiencyIn the realm of mineral processing, flotation efficiency is paramount, and Metso’s Concorde Cell stands as a testament to their commitment to pushing the boundaries of what is achievable.The Concorde Cell is an advanced flotation technology designed to optimise the mineral recovery process. It is a high-intensity pneumatic flotation cell that recovers unachievable fine and ultra-fine particles, resulting in significant revenue gains for mining operations. The Concorde Blast Tube is the core component of this new forced air technology. It produces very high shear and extremely fine bubbles for faster flotation kinetics and increased recovery in particles under the 25 microns range. Furthermore, Concorde Blast Tubes treat 100% of fresh feed combined with tailing recycling for improved performance, allowing for finer grinding to gain additional liberation without the risk of valuable particles being reported to tailings.Concorde technology benefits from induced supersonic shockwaves which exhibit notable attributes, including high energy dissipation and the generation of a finer distribution of bubble sizes. This phenomenon is observed as it contributes to enhanced efficiency in mineral flotation processes.The utilisation of forced air introduces a crucial advantage in mining operations, enabling the attainment of higher air-to-pulp ratios. This aspect is pivotal in optimising flotation conditions, resulting in improved particle recovery and separation efficiency.Enjoyed what you’ve read so far?
