Provided is a method for pretreatment of gold ore in order to leach out gold from gold ore containing pyrite, with which it is possible to suppress the generation of sulfide dioxide and to improve the leaching rate of gold. A method for pretreatment in order to recover gold contained in gold ore containing pyrite (FeS 2 ) by wet treatment, the method containing a step in which pyrite in gold
Jun 01, 2007#0183;#32;Chlorine had been used to dissolve gold from ores and concentrates, during the second half of the 19th century in Australia and North America. At the beginning of the 20th century, this process was gradually replaced by the more economical alkaline cyanide leaching (Sparrow and Woodcock, 1995). Nowadays, however, due to the realization of environmental problems of cyanide, there is a

Aug 12, 2019#0183;#32;HCl will not dissolve gold; gold is far below hydrogen in the reactivity series of metals, HCl in not a strong enough oxidizer to dissolve gold. Nitric acid can oxidize gold, or chlorine gas can oxidize gold (pry away an electron from golds atom).
It is obtained by mixing three parts of concentrated hydrochloric acid (HCl) with one part of concentrated nitric acid (HNO. 3. Moreover, it usually contains a halogen or even a certain amount of hydrogen peroxide to increase the dis solution rate. Upon dissolution in this media, gold forms the stable tetrachlo.
