Gold Chloride Market

While this is a common oxidation state for gold compounds, there also exists another related chloride of gold, with an oxidation state of (+1) Important properties of gold chloride include its solubility in water and ethanol, its hygroscopic nature, and its decomposition process in the presence of light or a temperature of more than 160 degree celcius...

Roasting in Metallurgy

In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution...
