About Dundee Sustainable Technologies, a company controlled by Dundee Corporation

DST is engaged in the development of technologies for the treatment of complex material from the mining industry. DST proprietary processes are applied for the extraction of precious and base metals and for the stabilization of contaminants, such as arsenic, from ores, concentrates and tailings, which cannot be extracted or stabilized with conventional processes because of metallurgical issues or environmental considerations.

At present, DST utmost technological advances are associated to the extraction of precious metals using chlorination. This process provides a cyanide-free alternative for the exploitation of gold deposits. The primary benefits of the innovative technology are shorter processing times, a closed-loop operation eliminating the need for costly tailings pond, reduced environmental footprint related to inert and stable characteristics of the tailings.

The chlorination process developed by DST is a recognized "green technology" for which it was awarded a $5.7 million grant for the construction and operation of a $25 million demonstration plant. The commissioning of the demonstration plant, with a capacity of 15 tonnes per day of concentrate is expected to be completed by the end of October 2015 and will serve as a platform for the chlorination extraction technology on an industrial scale.

In addition, DST is currently constructing a pilot plant for its arsenic stabilization process which calls for the sequestration of the contaminants in a stable glass form. This process is becoming an attractive technique to segregate the toxic material and is therefore opening opportunities for materials considered to contain too much arsenic to be exploited or stabilized using conventional approaches.

DST has filed, published and granted patents for these processes in several countries.
