The Gold Is Formed Into Gold Bars; Of course, this will depend on how the refined gold will be used. In most cases, however, the newly refined gold gets molded directly into gold bars. These are easy to store, transport and are easily marked based on weight and karat. How Raw Gold is Found and Refined
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.
