RESPONSIBLE MINING

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.

INNOVATIVE SOLUTION

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
Low-cost, scalable processing circuit
A complete mobile or fixed processing circuit
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
