Dundee Sustainable Technologies Inc is a Canada-based company engaged in the development of technologies for the treatment of materials in the mining industry. The Company has developed metallurgical processes based on a chlorination technology. It is a method of treating and extracting gold and/or silver and other base metals by creating a chloride with either chlorine or hydrochloric acid. Through the development of its processes, the Company extracts precious and base metals from ores, concentrates and tailings, while stabilizing contaminants, such as arsenic. The Company is focused on two primary processes: Gold Extraction by Chlorination, which is a process associated with the extraction of precious metals using chlorination to provide a cyanide-free alternative for the exploitation of gold deposits, and Arsenic Stabilization by Vitrification, which involves a technique to segregate arsenic and provides opportunities to process materials considered toxic to be exploited.
