CYANIDE-FREE GOLD EXTRACTION PROCESS
ABOUT US
The mining industry is facing growing pressure to improve its current practices and to develop environmentally-friendly alternative processes to reduce environmental liabilities. Several mining jurisdictions around the world have banned or restricted the use of cyanide. As a consequence, mining companies are struggling to obtain the permits for their projects due to increasing environmental and social concerns related to the use of cyanide.
The Corporation’s patented process is providing an alternative to the conventional cyanidation process for precious metal extraction.
The Corporation has developed a novel process which uses chlorination in order to extract precious metals from refractory minerals. The Corporation’s process operates in a closed loop circuit, which implies that no liquid effluents are generated, eliminating the need for costly tailings ponds. The chemistry and process design allows precious metal deposits containing base metals to be treated viably. The tailings from the process are inert from toxic substances, sulphide depleted and not acid generating, and as a result, meet environmental norms. The efficiency of the process has demonstrated high gold recoveries within a fraction of the time needed for cyanidation to obtain similar results.
