Gold: The mineral native Gold information and pictures
Gold is one of the heaviest minerals. When pure, it has a specific gravity of 19.3. Due to its weight, it can be panned because the Gold sinks to the bottom. In addition, it can be easily separated from other substances due to the weight differences. Gold is also the most malleable and ductile substance known. It can be flattened out to less than .00001 of an inch (less than .000065 cm), and a 1 oz. (28 gram) mass can stretch out to a distance of over 50 miles (75 kilometers). GoldGold mining - Wikipedia,18.12.2004· Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold.
