The gold found in pulled or discarded fillings, bridges and casting molds can be collected by dentists and sent to a recycler. The purity of dental gold is usually 16 karat, but it is slightly more complicated to recycle than jewelry because it may include nonmetal content like tooth enamel or porcelain.
Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold. To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods. Gold nuggets, a popular form of Gold with collectors, are formed when erosion causes a large piece of Gold to separate from its mother rock, and then gets carried into a stream or river.
