Cyanide-free gold recovery - CSIRO

19-02-2021  A commerative gold ingot from the first gold pour using our cyanide-free recovery method. The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production.

The World’s First Breakthrough Technology To

Traditionally, gold mining has depended on harsh chemicals such as cyanide and mercury to extract gold from ore. This has left our planet with a legacy of toxic waste which is harmful to health and the environment. For over 50 years, the industry and leading research institutions have been trying to find such an alternative without much success.

Sustainable Responsible Mining I Cyanide-Free Gold

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.
