Identifying Extraction Technology of Gold from Solid

The demand for gold in the field of national storage, jewelry, and electronics has never been higher However, gold extraction is not always welcomed by local residents because of the resulting environmental contamination For more than a century, cyanide and aqua reiga were dominantly used for gold mining because of their low costs, high efficiencies, and easy operationsThe demand for gold in the field of national storage, jewelry, and electronics has never been higher However, gold extraction is not always welcomed by local residents because of the resulting environmental contamination For more than a century, cyanide and aqua reiga were dominantly used for gold mining because of their low costs, high efficiencies, and easy operations In this article, anIdentifying Extraction Technology of Gold from SolidFOR GOLD EXTRACTION DUNDEE SUSTAINABLE TECHNOLOGIES 3700 rue du Lac Noir Thetford Mines, QC, Canada 4184237247 600 de Maisonneuve, Suite 2750 Montreal, QC, Canada 5148666001 wwwdundeetechnologies March 2014CYANIDEFREE PROCESS FOR GOLD EXTRACTION
