    The world39s gold production has changed over the past 30 years. The exploration and discovery of large, freemilling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, lowgrade deposits or look for smaller, often more complex ones in remote, often hardtoreach locations?

    Gold extraction QueensMineDesignWiki

    The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon and gold complex is sent to elution where it is washed, and transferred to electrolysis where the gold is fully recovered.

    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.
