costing of a gold ore processing

    How Is Gold Processed?

    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.
