GOLD LECHING FROM A SAUDI ORE BY THE NONPOLLUTING

Abstract: In all working Saudi gold mines, ores are treated using the hazardous cyanidation process. Some Saudi gold ores, such as Al-Amar, is known to be refractory to cyanidation. In this work, we have examined the extraction of gold from Al-Amar gold ore by the much environmentally safer and efficient thiosulfate process.

Recovery of Gold from Tailings of Al-Amar Mine in Saudi Arabia

The leaching efficiency of gold from some Saudi ores by the toxic cyanidation process is as low as 60-80%. Mining tailings of these ores contain considerable amounts of residual gold and toxic cyanide ion. These tailings are stored in massive ponds (tailing dam) containing considerable amounts of gold and pose environmental hazards.

Gold cyanidation Wikipedia

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

Cyanide Process Gold Cyanidation Process Gold Leaching

Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold. Since gold is soluble after the leaching process, it is free to move through the membrane while the rest of ore cannot pass through the membrane. Lime is added

In the cyanide process for extraction of gold and silver

Silver and gold are extracted by the cyanide process (Mac Arthur Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air.
