Apr 24, 2017· Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Its chemical properties make it useful for the manufacture of computers parts, electronics, jewelry and dental work. Some people find it profitable to attempt to extract the gold from these scraps, then refine and sell it.
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
The Chemistry of Gold Extraction provides the broad base of knowledge now required by all those working in the gold extraction and gold processing industries. The book bridges the gap between research and industry by emphasizing the practical applications of chemical principles and techniques.

EXCLUDING mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical .
Gold (Au), chemical element, a dense lustrous yellow precious metal of Group 11 (Ib), Period 6, of the periodic has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form.
A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of highgrade ore per year for 8 years. The deposit contains ounces of gold per ton of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore

It provides the broad base of knowledge that is now required by all those working in the gold extraction and gold processing industries.
Gold agglomeration is a technique that is used for the recovery of gold when it is impossible to use cyanide or mercury because of environmental concerns. The use of a process called coalgold agglomeration makes use of a slurry made from finely divided coal and oil that works on the principle that gold is a hydrophobic material that won''t be wetted by water but will be attracted to the slurry.
