Gold Rush Expeditions, Inc. is proud to present the Historic Telluride Chief Gold Mining Claim. This is a 20 acre lode mining claim for sale exclusively through Gold Rush Expeditions, Inc. The claim is located just outside of Kingman, Arizona and has been properly staked and marked at all corners.
Calaverite, or gold telluride, is an uncommon telluride of gold, a metallic mineral with the chemical formula AuTe 2, with approximately 3% of the gold replaced by silver. It was first discovered in Calaveras County, California in 1861, and was named for the county in 1868.
telluride gold ores are often somewhat refractory due to the presence of slow-dissolving gold minerals such as aurostibite, maldonite and gold tellurides. Carbonaceous ores: The gold is fine, and, usually, is predominantly associated with the sulfides (pyrite or arsenopyrite)
Abstract. 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.
Jan 02, 2011· Next are the telluride ores found in the lower regions of the mine. The majority of whatwill be shown is known as a PolyMetallic Replacement Deposite. This content rich ore not only contains pm/pgm, but also copper,zinc, lead, iron, and arsenic.
The Tuvatu gold–telluride prospect is one of several epithermal gold systems along the >250 km northeast trending Viti Levu lineament, Fiji, which are genetically associated with alkalic magmatism. Vein structures contain a variety of sulfides, native elements, sulfosalts, and tellurides.
The Telluride Chief Mine is a Gold mine with silver and Molybdenum deposits associated. The mine is sunk in the intersection of the Prince George and Banner lodes which have been noted for substantial gold values. The ore streaks are said to be 3-4' wide at any given section and up to 1000' long. The lodes do continue off the claim but the ...
Although gold telluride minerals were never actually found in the mountains near Telluride, the area's mines were rich in zinc, lead, copper, silver, and ores which contained gold in other forms. Telluride began slowly because of its isolated location.
are historically important ores of gold (and to a lesser extent silver), and are found in relative abundance within several of the world's major telluride districts. Detailed studies on the atomic structure of the

Gold-silver telluride minerals, and gold ores from Colorado Arguably, tellurium-rich gold ores are developed in Colorado as well as anywhere on Earth, both in economic terms (tonnage of contained gold) and in light of the occurrence of diverse well-crystallized mineral species.
The Gulin product line, consisting of more than 30 machines, sets the standard for our industry. We plan to help you meet your needs with our equipment, with our distribution and product support system, and the continual introduction and updating of products.
The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type.

Examine photos of natural gold ores and telluride gold specimens mined - Nevada Outback's gold This very large nugget gold specimen contains significant quartz and is from Alaska. It's rounded shape shows the signs of wear and tumbling in a river environment.
Calaverite is an uncommon and much sought after mineral by mineral collectors and those seeking fortunes. Calaverite is one of the few minerals that is an ore of gold, besides native gold itself. It is the most common gold bearing mineral besides native gold.
Prior to 1896, rocks containing tellurides were not recognised as rich gold ores, looking somewhat like pyrite (or fool's gold)-bearing waste, and were discarded, strewn on cart tracks and walkways, and also used as building stone.
Ironically, the gold ores were not calaverite or any other tellurium-containing compound. Commercial applications for tellurium, however, were not developed for almost another full century. During the 1960s bismuth -telluride, a thermoelectric, semiconductive compound, began to be used in refrigeration units.
J. Zhang et al., Processing technologies for gold-telluride ores 3 ing roast, carburizing roast, and sintering or blast roasting. The high temperature can sufficiently decompose the tellu-rides and leave behind the valuable gold residue.
1. Introduction. Gold–telluride ores have been treated commercially in only in a small number of regions in the world, most notably in Kalgoorlie, Western Australia; Vatukoula, Fiji; Cripple Creek, Colorado, and Kirkland Lake, Ontario.
Rebellious Ores: Sulfides, Selenides and Tellurides. Interested in solving the difficulties of dealing with rebellious ores and recover their gold and silver? Many types of valuable ores contain Sulfides, selenides or tellurides and they can make processing these ores more difficult. ... Sylvanite: A rich telluride of gold and silver. After ...
The tellurides can be precipitated either at the same place or separately from native gold ore, depending upon precipitation mechanisms, local setting, etc. Contemporary viewpoints for telluride formation include a Te-rich source, generally magmatically-derived, transport of Te as aqueous/vapor species within hydrothermal fluid, and ...
