When looking for gold in Californiawhat chracteristics would be the best way to distinguish gold from pyrite?
It can be identified in the field by the sulfur smell of the powdered mineral. Its metallic luster and pale-to-normal, brass-yellow hue have earned it the nickname fool's gold due to many miners mistaking it for the real thing, though small quantities of actual gold are sometimes found in pyrite. In fact, such auriferous pyrite is a valuable ore of gold.
What mineral property can be used to distinguish between pyrite and chalco pyrite?
Pyrite also known as "fool's gold" is a mineral that has both a different chemical, morphological and physical characteristics than gold. Gold is denser (i.e. the same size of gold is much heavier than the that of pyrite). Gold's average density is 17.64 g/cm3 while Pyrite's density is on average 5.01 g/cm3. The chemical formulas are different. Gold's chemical formula is "Au" while Pyrite's is and iron sulfate mineral with a formula of "FeS2". The color is also different, gold appears the color of gold while pyrite is more bronze in color. The crystallographic form of the minerals also vary. Gold is a very soft mineral while Pyrite is much harder (gold has a hardness of 2.5 while Pyrite is 6.5). To distinguish between a sample of each, you could scratch the surface of gold using your fingernail which you would not be able to do with pyrite. You can try to scratch it because pyrite or fools gold much harder then gold so if it doesn't scratch that much it is most likely pyrite or fools gold. You can tell them apart by looking at their reflection and streak. Also, gold is much more dense than pyrite, so the same volume would 'weigh' about 3.5 times more. Gold has a hardness of about 2.5, while pyrite is about 6 (Gold is softer and more malable). Streak is used to distinguish between Gold and Pyrite.
