Gold Returns NBER

Nevertheless, the uncertainty in gold returns is concentrated in the price change component. The model can explain the time varying volatility of real gold prices if preference shocks for gold services are small under the classical gold standard but large in other periods particularly because of shifting monetary roles for gold.

How Is Gold Processed? Reference

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
