Thiosulphate is an attractive alternative reagent to cyanide for processing gold ores. It is relatively cheap and non-toxic, forms relatively strong gold and silver complexes, and readily leaches gold ores in ammoniacal solutions, catalysed by Cu(II). It is particularly suited to carbonaceous ores where the recovery of gold by cyanide is poor.

The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve ...

Leaching Equipment. There are two primary categories of contacting method according to which leaching equipment is classified: (1) leaching may be accomplished by percolation and (2) the particulate solids may be dispersed into a liquid phase and then separated from it. Each may be operated in a batch or continuous manner.

Leaching Tank [Introduction] Cyanide leaching stirring equipment. [Volume] 6-1740m3 [Application] Double impeller leaching stirred tank is suitable for gold leaching, adsorption and other mixing operations with small specific gravity, low viscosity, slow settling speed, ore particle size more than 90% in 200 mesh and pulp concentration less than 45%. ...


Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the


takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in


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 …


Whether the leaching is performed in stirred tank reactors or heaps, the size and type of equipment needed for a thiosulphate leaching flowsheet is very similar to a conventional cyanide leach. SGS is a global technical leader in the field of thiosulphate leaching, and our laboratory and industry experts have spent years designing and developing


Gold leaching in thiosulfate solutions and its environmental effects compared with cyanide Oraby, Elsayed A. ( 2009 ) Nowadays, keeping mining and the environment sustainable is a …


Cyanide/Effluent Detoxification. Cyanco can analyze a customer's ore samples at our lab in Nevada by running leaching circuit optimization tests. For existing mines, we can imitate their leaching process in the lab, allowing for accurate testing of different detoxification methods. Based on those results, we create a full-scale circuit design ...


Non-cyanide gold leaching agent (also can be called Non-cyanide gold dressing agent or Non-cyanide gold dissolving agent) is mainly applicable to heap leaching, tank leaching, and carbon paste (agitation leaching) processes of fine grind gold and silver ore.


The complete copper pressure leaching process concept includes pressure leaching in an autoclave to produce copper-containing pregnant leach solution. Leaching is followed by a neutralization step and then copper solvent extraction and electrowinning. Gold and silver can be recovered by adding a lime boil step before cyanide leaching.


It is necessary to make sure the suitable leaching time in the cyanide leaching process. The leaching time is short, the gold mineral can't fully dissolve and leach; the leaching time is too long, it needs larger equipment and site deployed, and leads to the impurities dissolution and impeding the dissolution of gold.
