The funds use futures contracts to gain exposure and essentially provide a syntheticshortposition in the underlyinggoldminer stocks.

Leaching dissolves thegoldout of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in aprocessknown as carbon-in-pulp. As the cyanide and oxygen react chemically,goldin the pulp dissolves. When workers introduce small carbon grains to the tank, thegoldadheres to the carbon.

This process is a widely used process in China's gold plant, in which the recovery rate of gold can reach 30-60%. 5. Cyanidation (full mud cyanidation) process Applicable to gold with a higher emerald grain size, a deeper iron ore-bearing pyrite quartz vein type ore, or a gold-altered diorite-type ore.

Chlorination was a process of dissolving gold ores, after crushing and roasting, by the use of chlorine gas. In 1896, the cyanide process was introduced for the extraction of gold from finely crushed ores, concentrates and tailings by means of cyanide of potassium.

­The final stage ofgoldproduction -- refining-- involves removing impurities that remain after the smeltingprocess.Refining companies receive doré bars, as well as scrapgold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the puregoldfrom other precious and less precious metals. A sample is then taken to a lab for tests, or ...
