Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold …

How Is Gold Extracted From Gold Ore? | Sciencing

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Gold agglomeration is a technique that is used for the recovery of gold when it is impossible to use cyanide or mercury because of environmental concerns. The use of a process called coal-gold agglomeration makes use of a slurry made from finely divided coal and oil that works on the principle that gold is a hydrophobic material that won't be wetted by water but will be attracted to the slurry.

The Chemistry of Gold Extraction

­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.
