Gold Mining: Gold Mine Operations World Gold Council

During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine. In times of higher prices, mining lowgrade ore will become profitable as the higher price offsets the increased cost of extracting and milling

How Is Gold Processed? Reference.com

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.
