LEACHING SlamJet™ sparging is the most cost effective injection system for leaching processes The Process: In the cyanidation process for gold ores, metallic gold must form a cyanide complex during the process of dissolution according to the following reaction:

Cyanide is destroyed by sodium thiosulfate or sodium nitrite. An average fatal dose of HCN is about 5060 milligrams. Cyanide dissolves both gold and silver from alkaline solution. Cyanide is a very "clean" extraction system, as it does not extract many of the base metals such as iron.

Today, cyanide leaching is the method of choice for the recovery of most of the world''s gold production. There are however, many other chemical leaching processes that have been sporadically or historically used. In most instances, cyanide leaching will provide a more technologically effective and cost efficient method. Alternative lixiviants

New Technology for Recovery of Gold and Silver by Pressure Cyanidat ion Leaching and Electrocoagulation 73 subsequent liberation of gold and silver which would then be available for the cyanide ions. Pressure oxidation of pyrite and argentopyrite at low temperature (700C) and oxygen

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the

CNFREE ecofriendly gold leaching reagent is a kind of leaching reagent that can replace sodium cyanide without changing the original equipment and cyanide process. It can be used directly for gold ore beneficiation and refining.

Ore that contains free gold and/ or silver may not yield a sufficiently high recovery by sole use of cyanide leaching, due to a very long dissolution time for large metal particles. Such ore may first be subject to a gravity recovery process to recover the free gold and /or silver before being subjected to cyanide leaching.
