What is the MACH REACTOR™

The MACH REACTOR™ is game changing disruptive technology harnessing the power of cavitation, permitting chemical reaction and metal extraction that would otherwise not be possible.

Disruptive Technology

The MACH REACTOR™ is the only high shear/cavitating device currently on the market that is completely self-aspirating, allowing it to be operated without a pressurized gas supply.

The self-aspiration aspect, combined with the comparatively lower power draw, makes it particularly suitable to projects where power costs are high, or power is self-generated.

This disruptive technology is exactly what the metallurgical industry needs to improve production yields and profitability of marginal operations. It’s a different take on known principles to create technology that is vastly different from the traditional with unparalleled levels of efficiency.

“We have to do something different in order to survive as an industry.”

Available Models

The MACH REACTOR™ can be custom designed according to client specifications, for any flow requirements. A popular size for gold operations is 600m3/h slurry capacity.

The preferred installation of the MACH REACTOR™ is in-line with the flow into the first Leach Tank or on Tank Recycle.

  • Reactor life to match project life
  • Self-aspirating enabling low pressure gas injection

Where can the MACH REACTOR™ technology be applied?

The MACH REACTOR™ technology can be applied across a range of commodities, from environmental remediation through to metal extraction in hydrometallurgical plants. The technology may also be applied to conditioning and external aeration in a flotation application, where we achieve better selectivity and recovery at lower mass pulls – flotation euphoria! The MACH REACTOR™ is particularly effective in the recovery of valuable mineral fines in the order of five microns and lower.

The MACH REACTOR™ is particularly well suited to pre-oxidation and boosted leach applications in gold plants.

MACH REACTOR™ technology also finds application in the proprietary:

  • Gold Ore Hexate™ Refractory Gold Process
  • Gold Ore Hybrid™ Detox

The MACH REACTOR™ and its applications enjoys worldwide patent protection.

Testing facilities utilizing a scaled down laboratory size reactor are available at both the SGS Laboratories and Mintek in South Africa and at ALS in Perth.

The Power of Cavitation

Cavitation is not something normally applied within the metallurgical industry. Gold Ore has found a way to harness this powerful energy and use it for something good.

Chemical reactions are governed by the interaction of energy and matter. Imploding cavitating bubbles generate temperatures of up to 5,500°C and pressures of around 1,000 atmospheres, creating a highly reactive environment for mass transfer and chemical reaction. Re-entrant jets and the subsequent acceleration of particles and gases in heterogeneous systems approximate the speed of sound, hence the name “Mach Reactor”.
