sylvanite

It can also be processed from the mineral sylvite or sylvanite.

It occurs with native tellurium, rickardite, petzite and sylvanite.

It is also found in sylvanite, a mixture of sodium chloride and potassium chloride.

They include calaverite, sylvanite, nagyagite, petzite and krennerite.

Zemannite is a secondary mineral produced by weathering of native tellurium minerals, such as sylvanite or calaverite.

Both of the chemically similar gold-silver tellurides, calaverite and sylvanite are in the monoclinic crystal system, whereas krennerite is orthorhombic.

Tellurium is sometimes found in its native (elemental) form, but is more often found as the tellurides of gold (calaverite, krennerite, petzite, sylvanite, and others).

Wright had sold the claims that became Sylvanite to Harry Oakes in exchange for Lakeshore property, shares in the mine and a vice-presidency.

There are a few dozen tellurate minerals and telluride minerals, and tellurium occurs in some minerals with gold, such as sylvanite and calaverite.

Associated minerals include sylvanite, hessite, altaite, petzite, empressite, native tellurium, native gold, galena, sphalerite, colusite, tennantite and pyrite.

It is commonly associated with native gold, hessite, sylvanite, krennerite, calaverite, altaite, montbrayite, melonite, frohbergite, tetradymite, rickardite, vulcanite and pyrite.

Gold sometimes occurs combined with tellurium as the minerals calaverite, krennerite, nagyagite, petzite and sylvanite, and as the rare bismuthide maldonite (AuBi) and antimonide aurostibite (AuSb).

It was named for the County of origin by chemist and mineralogist Frederick Augustus Genth who differentiated it from the known gold telluride mineral sylvanite, and formally reported it as a new gold mineral in 1868.

It is found in large quantities in ores made up of intergrown tellurium, calverite or sylvanite, melonite and altaite, as anhedral grains either enclosed in single crystals of tellurium or localized along grain boundaries in tellurium aggregates, among others (Kelly and Goddard, 1969).
