Clean Mining: Cyanide-free gold processing technology

In June 2019, Clean Mining launched a cleaner and safer processing solution for gold miners, which has the potential to transform the gold sector and responsible mining globally. The innovative and cost-effective solution replaces toxic sodium cyanide, used in gold processing since 1887, with an inorganic compound known as thiosulphate, which acts as a reagent when used with Clean Mining's innovative leaching and de-watering processes.

The low-environmental impact solution, originally developed over more than a decade by Australia's national science agency - CSIRO, was proven in trial at an industrial scale before being launched and promoted to miners of all scales this year, although marketing and production activities have since been focused on small to medium miners as existing cyanide-based circuits cannot simply be ‘upgraded' to use thiosulphate.

Since the launch of the new mineral processing solution, Clean Mining has been inundated by interest from the gold mining sector and substantial work has progressed to develop a reliable, ethical, quality and affordable supply and global distribution chain, with a particular focus on refining the design and construction of the tank leaching systems and economical dewatering solutions. This will enable dry-stacked tailings and eliminate the need for tailings dams and the impacts they have on the environment. In addition, when installed as a complete solution, the Clean Mining product also enables the re-use of thiosulphate and water utilising the de-watering process - further benefiting the Earth.

The solution is also scalable and potentially mobile, making it affordable and opening up financial access to miners who may have otherwise been constricted to adopt clean production processes and/or progress their exploration efforts to the processing stage.
