It is possible to detect gold with a specially designated metal detector. A prospecting detector can find gold as small as a half a grain. As the size of the gold becomes larger, gold nuggets can be located at deeper depths. A single grain nugget can be found at a depth of 1-2 inches.

Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.

Step 1: Milling. When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock.
