The challenge for all these alternative lixiviants is they have to offer comparable leach kinetics, be environmentally friendly and cost effective. The problem is even though some may solubilize metals, they are typically not stable and only work in selective environments. Consider the e-waste sector. We're competing against high temperature acid baths, which are essentially aqua regia. Yet we're getting similar results with our formula at ambient temperatures compared to 50 degree centigrade aqua regia. But ours you can basically drink. The chemistry is unique insofar as it is inorganic electrochemistry. We combined various chemicals and elements to form new compounds and gold processing plant. I can't really comment too much more on the ingredients at this time.
The word ¡®cyanide¡¯ can stir people¡¯s emotions. This is not surprising, given the less desirable aspects of its historical use, and the many myths and misconceptions relating to cyanide.
The cyanide process of gold recovery enabled a higher percentage of gold and silver to be extracted from hard rock, making many operations viable that would otherwise have had to close. The world class Martha Mine has a history spanning three centuries Rare Earth Minerals Processing Plant. Together with its historic use up to 1952, the Waihi mining operations have used cyanide since modern operations began in 1988. A substantial database spanning more than 20 years of modern use demonstrates that cyanide can be transported, stored, used and disposed of in a safe manner, with no significant adverse effects on the environment.
