Gold Cyanidation Ground Truth Trekking
Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

By using our REFINEIT system, all the user has to do is melt the gold in an ingot, submerge the gold in the gold refining equipment we provide, then wait.
Gold Smelting Process | Sciencing
Apr 24, 2017· Gold is purified by means of a smelting process, which utilizes pressure, high heat and chemicals to accomplish the task. Like any metal that appears naturally in the earth, there are impurities that must be removed. Removing minerals and other impurities allows gold to be used in its purest form, which is necessary ...
Cyanide Wikipedia
Hydrogen cyanide may be produced in the combustion of polyurethanes; for this reason, polyurethanes are not recommended for use in domestic and aircraft furniture. Oral ingestion of a small quantity of solid cyanide or a cyanide solution as little as 200 mg, or exposure to airborne cyanide of 270 ppm, is sufficient to cause death within minutes.
Gold and Platinum Refining Recovery Systems / Equipment
An overview on how to refine precious metals. There are many kinds of materials that yield pure gold, platinum, or silver when refined. Though it's usually a little intimidating the first time you do anything, refining precious metals yourself is relatively easy to do (even with no experience) provided you have the right information, supplies, and equipment.
Managing cyanide: health, safety and risk management ...
Cyanide was first used in the Turkish mining industry in 1987 at a staterun silver plant. Today, approximately 2500 ton of sodium cyanide are used annually in Turkey for gold and silver recovery, including 1100 ton/y used at the Kutahya Gumuskoy silver plant. The Ovacik gold mine uses some 120 ton of sodium cyanide alone .
