Microchemical analysis is then used when necessary to confirm the identity of the mineral. It has been the writer's experience that etch tests on tellurides are not particularly reliable, due probably to the fact that it is rarely possible to place a drop of reagent within the area occupied by a single telluride mineral.

"Rock of the Month #158, posted for August 2014"--- 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 telluride fused, leaving a characteristic island of telltale gold surrounded by a pool of tellurium oxide. Gold-bearing tellurides are silvery to pyrite-yellow, commonly striated, unlike gold, which is a deeper yellow and rarely crystalline. Some mineral indicators of gold tellurides were observed that assisted in its detection.

Gold–(silver) telluride deposits normally contain a dozen or more different telluride and selenide minerals and present complex ore textures. An example is seen in the ores of the recently discovered Sandaowanzi gold deposit, where sylvanite is the most abundant gold-bearing mineral and together with petzite and krennerite accounts for >60% ...
The mineral is a mercury telluride compound formed when mercury fuses with tellurium, another extremely toxic and rare metal. Coloradoite therefore poses a doubly toxic threat to anyone daring to handle it. The combination of the two elements poses the risk of serious poisoning if carelessly handled. If heated or chemically altered, deadly ...
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.

Bismuth (III) telluride (Bi2Te3) is a thermoelectric material, which acts as a topological insulator: a quantum material with an insulating bulky gap and gapless edge. It forms thin films by different techniques, which include chemical method, electrodeposition and molecular jet method. The binary chalcogenide, bismuth (III) telluride occurs as ...

Mineral characteristics Carbonate minerals and quartz are dominant in banded, symmetrical veins. Ore minerals form groups of blades or small masses and locally, open-space fillings in vugs. In veins, complex intergrowths of several telluride minerals are common. In some case, minerals are so complexly intergrown that they cannot be easily ...

Sylvanite: A rich telluride of gold and silver. After calaverite, sylvanite is probably the next most important telluride ore mineral. It can assay as high as 30% gold. It is found with other telluride minerals in some precious metal ore deposits. Petzite: A gold and silver telluride that is mostly silver. Silver content is usually three times ...
This mineral is a mercury telluride compound formed when mercury fuses with tellurium, an extremely toxic and rare metal. This looks like the mineral was discovered in Telluride, Colorado, but I have found no reference to this. Interestingly, Coloradoite may be mined for its tellurium content because tellurium readily combines with gold ...
Like many towns in Colorado, the box canyon village of Telluride has its late 19th-century roots in mining. There was indeed "gold in them hills," though interestingly enough, never actually the mineral for which the town was named.
