Composition of Gold Alloys in Colored Gold Jewelry

When you buy gold jewelry, it isn't pure gold. Your gold is really an alloy, or mixture of metals. The purity or fineness of gold in the jewelry is indicated by its karat number24 karat (24K or 24 kt) gold is as pure as gold gets for jewelry. Gold that is 24K is also called quotfine goldquot and is greater than 99.7% pure gold.

Geochemistry of hydrothermal gold deposits A review

3. The geochemical behavior of gold in hydrothermal systems. The occurrence of gold mainly depends on temperature, pressure, pH values, Cl concentration, and fugacity of H 2 S in a hydrothermal system. Gold mostly occurs as AuCl 2 in a system with temperature higher than 400 176C (Gammons and Williams Jones, 1997), and with decreasing temperature being the primary mechanism causing gold
