How To Identify Gold Ore (Tips and Scientific Tricks)
Determining the specimen's density is one of the first steps in recovering gold from gold ore. Knowing the density of the ore makes the process more effective. The density of gold ore varies from one type to the next. Typically, impure gold is around 16 to 18 times heavier than its associated host rock, which has a density of 2.5.

How Is Gold Extracted From Gold Ore? | Sciencing
The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press. For the carbon-in-pulp method, the ground ore is mixed with water before cyanide is added. Then carbon is added to bond with the gold. The carbon-gold particles are put into a caustic carbon solution ...
