Dundee Sustainable Technologies Inc. is engaged in the commercialization of environmentally responsible technologies for the treatment of complex materials from the mining industry. Through the development of patented, proprietary processes, the GlassLock Process and the CLEVR Process, it extracts precious and base metals from ores and concentrates, while stabilizing contaminants, such as arsenic, antimony, and cadmium from ores and concentrates. It has designed, built, and patented a method for the permanent stabilization of arsenic from numerous sources, including arsenopyrite, enargite, cobaltite, flue dusts and environmental remediation. It has demonstrated its GlassLock Process onsite at an operating copper smelting in Namibia, Africa. It has developed an advanced process for the extraction of precious and base metals using sodium hypochlorite to provide a cyanide-free alternative for the exploitation of gold deposits. The CLEVR Process operates in a fully closed loop.
