Which is the main ore of gold?
Calaverite
What mineral group is calaverite in?
Calaverite is in the sulfides class and its subclass is tellurides.
What is the common gold ore?
Calaverite , Sylanite ,Nagyagite , Petzite , Krennerite are some of the ores of gold but i don't know how about common ores of gold
What are the principal gold ores?
The principal ores are calaverite, a telluride (containing tellurium) containing 40 percent gold, and sylvanite, a mixture containing 28 percent gold
What is the chemical formula of gold mineral?
Gold generally exist in nature as a pure metal; several gold minerals (without industrial importance) are săcărîmbit, sylvanite, krennerite, calaverite, petzite.

What is the compound name for Au2O3?
If it existed it would be gold(II) oxide. The stable gold oxide is gold(III) oxide Au2O3
What ore is gold found in?
Gold is mostly found in it's natural form as gold nuggets, fine grains or flakes, or as grains or microscopic particles embedded in other rocks. Ores in which gold occurs in chemical composition with other elements are comparatively rare. They include calaverite, sylvanite,nagyagite, petzite andkrennerite.
What other minerals are often found in ore that contains gold?
In nature, gold most often occurs in its native state (that is, as a metal), though usually alloyed with silver. Native gold contains usually eight to ten percent silver, but often much more - alloys with a silver content over 20% are called electrum. As the amount of silver increases, the color becomes whiter and the specific gravity becomes lower. Ores bearing native gold consist of grains or microscopic particles of metallic gold embedded in rock, often in association with veins of quartz or sulfide minerals like pyrite. These are called "lode" deposits. Native gold is also found in the form of free flakes, grains or larger nuggets that have been eroded from rocks and end up in alluvial deposits (called placer deposits). Such free gold is always richer at the surface of gold-bearing veins owing to the oxidation of accompanying minerals followed by weathering, and washing of the dust into streams and rivers, where it collects and can be welded by water action to form nuggets. Gold sometimes occurs combined with tellurium as the minerals calaverite, krennerite, nagyagite, petzite and sylvanite, and as the rare bismuthide maldonite (Au2Bi) and antimonide aurostibite (AuSb2). Gold also occurs in rare alloys with copper, lead, and mercury: the minerals auricupride (Cu3Au), novodneprite (AuPb3) and weishanite ((Au,Ag)3Hg2).
