What gives the MACH its MAGIC ..What gives the MACH its X-Factor?
For leaching operations, the pico-bubbles formed in the MACH may be ventilated with oxygen gas and evenly dispersed throughout the pulp through the intense mixing in the venturis of the MACH.
Apart from improving dissolved oxygen levels, which are critical for many leach operations, including the cyanidation process in gold leach operations, the extreme energy released during cavitation may cause:
– Particle breakage to improve liberation,
– Surface cleaning to remove passivation layers and coatings,
– Boundary layer reduction to improve mass transfer.
Hence the MACH can reduce reagent consumption including cyanide consumption as well as improve leach kinetics and recoveries to provide for a step-change improvement in project economics.
The MACH is pure science! 👨🏽🔬🤩
For MACH enhanced flotation, this is cleverly effected in the MACH REACTOR, which is able to render micron size particles amenable to flotation. These micron-sized particles would otherwise be lost to flotation tails.
As slurry velocities in the high-speed venturis of the MACH soar above a certain critical velocity, the instantaneous pressure in the venturi falls to below water vapour pressure, causing the nucleation of tiny cavities on the surfaces of the micron-sized hydrophobic particles.
These cavities may then be ventilated with the selected gas, usually air for flotation but may also be nitrogen or CO2, coating the hydrophobic surfaces with tiny bubbles in the size order of pico-, nano-, and micro-bubbles.
An aggregation effect of the micron-sized particle bubbles is catalysed by the intense mixing in the MACH, as particles move to lower energy states. These aggregates, which present as larger more floatable particles to flotation, can now be successfully floated with the MACH.
The MACH is able to be retrofitted onto any flotation cell giving it great versatility with application and installation. The MACH is an easy add-on to conventional flotation cells.
Don’t waste time, and don’t waste those precious metals either!🥳 🙌🏽
