Environment: Cyanide-free gold processing solution launched

The company works to transform gold production worldwide in an environmentally responsible manner. The innovative, cost-effective process replaces cyanide with a safer, less hazardous chemical reagent, thiosulphate. This inorganic compound helps dissolve fine gold out of ores into a solution, which can then be recovered through further processing.
