The company works to transform gold production worldwide in an environmentally responsible manner. The innovative, costeffective 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.

Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold. The cyanide process is as explained belowThe ore is grounded and crushed.
