Although most gold is produced from alluvial and other surface mining, or from underground reef mining, some gold is produced as a by-product when copper, lead, and uranium ores are refined. An estimated 30 percent of the gold in the U.S. is produced by these means. The exacting process of refining gold.
The gold wires enclosed lumps of schist and clay from the soil as they grew. Alluvial mining is technically simpler than hard-rock mining, so alluvial mining dominated Otago's gold mining history. Alluvial gold occurs as loose particles in the gravel, and is therefore easy to separate because of the high density of the gold.
