Gold is scattered in magma and magmatic rocks, but hydrothermal gold deposits (quartz gold-bearing veins, and so forth), which are important industrially, are formed from hot waters in the earth’s crust. In ores, gold occurs mainly in the free (native) state and only very rarely forms minerals with selenium, tellurium, antimony, and bismuth. Pyrites and other sulfides frequently contain an

2 INTRODUCTION For the past century gold has been recovered using cyanidation processes. Of these, cyanidation followed by carbon adsorption has been the dominant technique for gold recovery since the 1980’s. The success of the cyanidation process is due to the selective leaching of gold by cyanide. Some
