2016-1-1 Treatment of telluride ore began in Vanuwtu, Fiji, in 1934 using a conventional refractory treatment circuit using roasting followed by cyanide leach of the calcine. A hydrometallurgical treatment method for the leaching of gold telluride along with the production of tellurium metal was devised at Emperor Gold Mine (Cornwall and Hisshion, 1976). The process (called the Emperor Process) used a

2016-9-7 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 may be amenable, and finally treated by agitation in cyanide solution in the ordinary way.
Gold–(silver) telluride minerals in gold deposits are considered refractory ores from a mineral processing perspective, as they are not efficiently leachable in cyanide solutions. Therefore, additional processing steps are required to improve gold recovery when tellurides are present in the ore (e.g., [18,19]). Fine grinding and pretreatments (normally roasting gold tellurides at temperatures ≥800 °C) are generally utilized to improve gold

S. Ellis, G. Deschênes, in Gold Ore Processing (Second Edition), 2016. Abstract. Gold telluride ores, treated commercially in various regions in the world, most notably Kalgoorlie, Western Australia; Vatukoula, Fiji; Cripple Creek, Colorado, and Kirkland Lake, Ontario, exhibit slow leaching kinetics. There are many telluride mineral species and the most common gold bearing varieties include calaverite,

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. This caused most of the Telluride
