GlyCat™ is a patented gold leaching technology from Draslovka which combines glycine (a non-toxic chemical), with sodium cyanide for the recovery of gold & other precious metals.

GlyCat™ excels at handling high cyanide consuming ores containing base metals and pyrite, because glycine acts synergistically with cyanide through smart chemistry that results in significantly less cyanide being required to leach gold and other precious metals.

Benefits of GlyCatTM:

  • Reduces cyanide consumption by up to 90% and processing costs by up to 50%.
  • Economical gold extraction from ores with elevated soluble copper.
  • Reduces or eliminates cyanide detoxification requirements.
  • Minimal dissolution of contaminants.
  • Increases efficiency in the leaching process and improves recovery from some minerals such as tellurides.
  • Easily introduced to existing CIL/CIP circuits without major modification, as it is simply a change in the chemical blend.
  • Low risk, no CAPEX trial: you can effortlessly move back to conventional cyanidation if desired

As a primary reagent, glycine is environmentally friendly and can be recycled and re-used, providing a major cost advantage over and above the reduction of cyanide consumption.

About Glycine Leaching Technology:

Developed with Curtin University, GLT is a revolutionary new metal leaching technology which combines glycine (a non-toxic chemical), with sodium cyanide for the enhanced recovery of metals.

As a primary reagent, glycine is environmentally friendly and can be recycled and re-used, providing a major cost advantage over and above the reduction of cyanide consumption.

  • Glycine is a non-toxic amino acid that is fully bio-degradable. It’s used as a food additive for both humans and animals and has sugar-like appearance.
  • It is unique in its ability to selectively leach certain base and precious metals such as gold, copper, nickel, cobalt and silver.
  • Glycine is non-volatile and stable under typical gold leaching conditions.
  • It’s not chemically consumed. As a primary reagent, it’s recoverable and recyclable, providing a major cost advantage.
  • It’s effective with starved levels of cyanide for complex gold ores (gold ore with elevated base metals), and free milling gold ores. 

Our Engagement Model:

Our engagement process consists of a series of stages to guide and showcase the benefits of this new process compared to cyanidation:

  • DISCOVERY TESTS – sample tests are conducted at our innovation center in Australia to ensure viability of our process for your operation.
  • RISK REDUCTION TEST – process conditions are refined & a benefit estimate is provided. This can be done onsite, at a certified lab or at our center.
  • PILOT DEMONSTRATION – this can be done onsite, at a certified lab, or at our center in Australia.
  • TRIAL – trials are conducted at the plant (or at a large scale) to validate operational suitability.
  • IMPLEMENTATION – Draslovka grants a commercial user license, the technology is implemented and ongoing support is provided.
