A simple but important choice – business as usual or processing using, a commercially viable alternative to cyanide that can enhance environmental and social outcomes.

clean gold certified
The Clean Mining gold recovery process, developed by Australia’s CSIRO, replaces cyanide and mercury with a safer, less hazardous chemical reagent. This alternative gold recovery solution is non-toxic and dissolves fine gold out of ores into a solution, which can then be recovered through further processing.


What is our non-toxic solution?

This gold recovery agent is an inorganic compound – non-toxic, non-flammable and water soluble. While others have identified similar compounds previously, the Clean Mining technology, developed by the CSIRO, is applicable to a range of ores for responsible mining operators.
Clean Mining technology is particularly attractive to socially and environmentally responsible junior producers who don’t want the compliance and rehabilitation costs associated with cyanide. Clean Mining, for example, offers a mobile/transportable and scalable plant design that is ideally suited to small, high-grade deposits that might otherwise be stranded.
Using the patented Clean Mining solution to recover gold:
  • Is safer and more environmentally-responsible
  • Delivers similar gold recovery rates to cyanide
  • Means miners can re-use the reagent
  • Produces less hazardous tailings (with the potential to eliminate tailings dams)
  • Is better for the health and safety of mine employees, the environment and local communities


Overall, the patented technology offers:
  • A safer, viable ore processing alternative to cyanide
  • A solution that can be used on many different ores
  • A gold recovery rate comparable to cyanide
  • A simple gold recovery process
  • No cyanide-contaminated tailings dams
In terms of plant, it offers:
  • Ease of transition. The front-end milling circuit that is the same as a cyanide-based plant – so the new technology applies only from the leaching to gold recovery phases
  • An option for a de-watering process to produce dry tailings
Rehabilitation benefits include:
  • A reduced mining footprint
  • Reusable water and reagent
  • The option of the immediate repatriation of dry tailings
  • No risk of toxic cyanide contamination and spill
