Cyanide Leaching Chemistry Gold Cyanidation

06/02/2015· These particles are usually described as electrum which is a gold silver alloy containing 15 to 35% silver. Inasmuch as gold silver alloys of this composition are almost as soluble in cyanide as gold is, it is probable that some other factor has affected the solubility of the electrum particles. Possibly some other alloying element has influenced their solubility in

Improvements in gold ore cyanidation by pre oxidation

Leaching of gold or silver from these sources, which are named refractory and are typically low grade, can be complicated due to one or more of the following effects: kinetic or thermodynamic impediments on cyanide diffusion or on the dissolution of minerals, readsorption of leached gold or silver , and excessive cyanide consumption

Processing of High Silver Gold Ores ScienceDirect

01/01/2016· The most convenient processing alternative for high silver gold ores and concentrates is largely dependent on the quantity and mineralogy of the silver phases present. As far as leaching is concerned, pretreatment of the ore or modification of the leaching chemistry may be necessary to remove or diminish the negative effects of stable precipitating

Extraction of silver from a refractory silver ore by sono ...

01/05/2020· The leaching behaviour of silver from a sintering dust using the ultrasound assisted thiourea leaching was studied by Chang et al. , and they found that the silver recovery was almost 95% with shorter leaching time, while 89.9% with direct thiourea leaching. Therefore, it was envisaged that the use of ultrasound in the cyanidation can play a significant role on
