Tellurium Minerals in New Mexico - geoinfo.nmt.edu

Secondary tellurium oxides are predominantly limited to one deposit in New Mexico, the Lone Pine mine. At this locality, pyrite and tellurium dominate the ore mineralogy, and a very diverse suite of tellurium oxide minerals occur in oxidized quartz-tellurium-gold veins. It is the type locality (Williams, 1979) for the mineral Rajite [CuTe 2 O 5 ...

Kinetics of leaching selenium from Ni–Mo ore smelter dust ...

The kinetics of leaching selenium from Ni–Mo ore smelter dust in H 2 SO 4-HCl-H 2 O system was investigated. The effects including leaching temperature and time, particle size of the smelting dust, stirring speed, acid concentration and the coefficient β (the molar ratio of sodium chlorate to selenium in the smelter dust) on leaching of selenium were studied.

Site Information

The facility began smelting copper and gold tellurium ores from the Le Roi Mine in Rossland, British Columbia, and copper, lead, and silver ores from northeastern Washington in 1896. Heap roasting of tellurium ore involved open roasting on brick platforms. Burned ore was placed in a furnace that produced iron and slag waste.

Metal Profile and Properties of Tellurium - The Balance

Apr 21, 2018· Naturally occurring tellurium is more rare than gold, and as difficult to find in the earth's crust as any platinum group metal (PGM), but due to its existence within extractable copper ore bodies and its limited number of end-uses tellurium's price is much lower than any precious metal.

Treatment of Gold–Telluride Ores - ScienceDirect

The smelters operated as copper or silver lead smelters but were adapted to deal with shipments of gold ore. Eventually, in 1903, a local smelter was built on the coast at Fremantle, ∼600 km from Kalgoorlie. Some of the sulfo-telluride ores mined between 1897 and 1900 were very rich indeed, grading around 500 g/t.
