Aug 16, 19950183;32;The quantity of Au detected on the pyrite from a solution containing a high gold(I) concen tration is lower than that of a similar Au(III) solution. Elec trochemical studies of Schalch et al. (1976) and Nicol ( 1976 ) indicate that the rate of Au(1) reduction on metallic gold is considerably higher than that for Au (IIl).

Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent.

Pyrite The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
