How Is Gold Extracted from Ores?

Answer

Gold is extracted by first getting the gold ore from the mines. Then separating the impurities from the real gold and this is usually done using cyanide. The gold ore is placed into a tank that contains a weak cyanide solution, zinc is added and a chemical reaction which separates the gold from the ore. Pure gold is removed from the solution with a filter press.

Gold is extracted from ores through the use of cyanide. Ore is put into a tank containing a weak cyanide solution and zinc is added and the chemical reaction separates the gold from the ore. Another method of extraction is the carbon-in-pulp method whereby the ore is mixed with water before cyanide is added. Carbon is then added to bond with the gold and the carbon-gold particles are put into a caustic carbon solution, separating out the gold.
