Gold extraction - Wikipedia
Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience preg-robbing: the absorption by carbonaceous components which preferentially absorbs gold and gold-cyanide complexes. Leaching through Bulk Leach Extractable Gold or BLEG is also a process that is used to test an area for gold
Gold Ore Leaching Process Rubber Lining
Processes Of Mining Gold Cafeole Koeln. A slurry of ground ore water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved.Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver.This process removes 93 of the gold and 70 of the silver.

Gold Heap Leaching Process - xinhaiepc.com
Heap leaching HL is a flexible and economic mineral processing method commonly used to extract gold from low-grade gold ores. In this process ore is firstly crushed to fine particles. By spraying leaching solution to the large piles the gold-containing solution is leached.
Processing Gold Ores Using Heap Leach-Carbon Adsorption Methods
The chemistry involved in the dissolution of gold in the heap-leach cya- nidation treatment is the same as that for the agitation-cyanidation process. In heap leaching the oxygen essential for the dissolution of gold is intro- duced into the cyanide solution as it is being sprinkled upon the ore heap.
The leaching and adsorption behaviour of gold ores
from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from copper-cyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide& 39;s fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.
Dual lixiviant leaching process for extraction and recovery
Cyanide leaching has been the predominant process for gold extraction from mineral resources for more than a century Hilson and Monhemius 2006 Li et al. 2012b Örgül and Atalay 2002 . The major reasons for the acceptance of cyanide over the other lixiviants include higher chemical stability lower cost and better understood chemistry
Gold Cyanide Leaching Process Gold Cyanidation Process
All-slime cyanidation technology is a technology process which put activated carbon into pulp and leaching with absorbing gold at the same time. It includes the stages such as leaching pulp preparation leaching and adsorbing gold removal carbon recycling pulp agitation and gold loaded carbon desorption.

Gold is not active metals in the process of cyanide leaching gold can be under the action of oxygen and cyanide complexation reaction CN produce a water-soluble melamine aurous acid salt complex Au CN 2- so the cyanide agent is a key factor determine gold dissolved in general to ensure that a certain amount of free cyanide in the
Improving the gold leaching process of refractory ores using
The Albion process is an atmospheric leaching process for processing zinc concentrate refractory copper and refractory gold . This process is an integration of the Ultra-fine grinding UFG and oxidative leaching at atmospheric condition Mike Hourn 2014 . “The Leachox Process is essentially a range of established and new unit process steps
Maelgwyn Minerals’ Leachox Refractory Gold Process hits
To compare process routes and recoveries pressure oxidation can completely breakdown the sulphides and then achieve high gold recoveries maybe greater than 95%. Where as with the Leachox process and the partial oxidation depending on the nature of the mineralogy recoveries in the range 80% to 90% can be expected.

Very interesting info on Theo leaching. Thanks to all . I have access to several hundred lbs.of broken china and glass per week all with 24-22k gold trim/plating. I have been using HCL-Cl to remove the gold then dropping it with SMB. But with this method I end up with a lot of HCL which I reuse/recycle in a variety of ways.
