gold telluride extraction

Metallurgy for Recovering Gold from Telluride Ore

Gold ore associated with Telluride is hardly soluble in ordinary cyanide solutions and special treatment is necessary for its extraction. There are two methods in use in such cases. Roasting The ore is ground dry to about 30 mesh and roasted; it is then ground to a slime in water or cyanide solution, usually in grinding pans, utilizing the opportunity simultaneously to amalgamate any gold that

Telluride Colorado Western Mining History

Telluride History The town of Telluride, on the headwaters of the San Miguel River, is a quintessential western mining town. Probably named when a prospector mistook a rock sample for telluride ore (a type of rich, complex gold ore which was actually not what he had found,) the area experienced a gold rush starting in 1875 however its history reaches back much further.

Calaverite (gold telluride) Western Australian Museum

Therefore, extracting gold from telluride minerals, such as calaverite, which contains around 42% gold, has been very important in the history of Kalgoorlie mining, producing around 300 tonnes of gold. Gold-bearing tellurides were first identified in the Golden Mile deposits in May 1896, three years after the first discovery of gold.

Processing technologies for gold-telluride ores

The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].

Method to extract gold from telluride ores and concentrates

For the extraction of gold from telluride ores in practice, the use of melting on the lead or copper collector. If you cannot melting telluride ore lanroot in special modes. Alternative smelting is firing tellurite and cyanide leaching of the calcine. Direct cyanide leaching of gold from telluride ores slow.

(PDF) Hydrometallurgical Recovery of Tellurium

Extracting and recovering the tellurium is a second priority to the extraction of the gold, however the telluride ores, notably calaverite (AuTe) are not amenable to direct cyanization as the bond

Roasted Gold Telluride Ore from Cripple Creek, Colorado

A piece of roasted gold ore from Cripple Creek, Colorado. You will notice that the gold is formed into an almost bubbly showing on the surface. This was a result of a roasting process that was commonly used in this part of Colorado to process the telluride-rich ores from the mines.

Processing technologies for gold-telluride ores SpringerLink

Gold telluride ores are important gold refractory ores due to the presence of sulfides and other gangue materials. The classification and main physical properties of gold telluride ores were described, and possible treatment methods including flotation, leaching, and oxidation were reviewed. The results show that flotation procedures are much easier for gold tellurides compared to other

Iron interfering with gold wavelength during analysis was overcome by back extraction of iron from the organic extract. Centrifugation of colloidal materials in the organic phase also affects aspiration of solutions in F-AAS.

Mineral Transformations in Gold–(Silver) Tellurides in the

Gold–(silver) telluride minerals constitute a major part of the gold endowment at a number of important deposits across the globe. A brief overview of the chemistry and structure of the main gold and silver telluride minerals is presented, focusing on the relationships between calaverite, krennerite, and sylvanite, which have overlapping compositions.
