2012-12-31The chemical element gold, atomic number 79, symbol Au from the Latin aurum, is a soft, lustrous yellow, malleable metal. It is one of the transition metals and its atomic weight is 196.967 it belongs to group 1B in the periodic table along with copper and silver.
Gold is around 8 times heavier than the quartz rock which it is commonly associated with when gold is found in hardrock form. A single cubic foot of gold will weigh approximately 1187 pounds. It is this quality of gold, having a superior weight factor over the other materials usually found along with it, that is used in most gold recovery methods.

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 B.C. , when early Egyptians the Sumerian culture of Mesopotamia used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5100 of an ounce of gold
