Feb 07, 2015· Relative Rates of Dissolution of Gold, Silver and Their Alloy. Using 100 ml. volumes of 0.10 per cent NaCN solution, with surface areas of the metals and their alloys measuring 10 sq. cm., and with a constant volume of air for aeration and agitation, it was determined the relative rates of dissolution of gold, silver and two goldsilver alloys.

Direct cyanidation of silver sulfide by heterolytic CCN

Extraction of silver as silver cyanide from silver sulfide was made possible using acetonitrile as the source of cyanide. The process of cyanidation took place through the oxidation of sulfide to sulfur oxides and cleavage of the CCN bond of acetonitrile. The reaction

Silver (Ag), like gold, crystallizes in the facecentred cubic system. It melts when heated to 962 °C (1,764 °F). With a density of 10.49 grams per cubic centimetre, it is the lightest of the precious metals. It is also the least noble of the precious metals, reacting readily with many common reagents such as nitric acid and sulfuric acid.

Gold and Silver Leaching by Cyanidation

Apr 18, 2016· The basis of the cyanide process is that weak solutions of sodium or potassium cyanide have a preferential dissolving action on small particles of metallic gold and silver over other materials usually found in gold ores. However, there are a few minerals known as cyanicides that have deleterious effects which are discussed later.
