Simple Methods of Gold Purification
The purification of such alluvial gold alloys is a simple matter. The high specific gravity of the metal allows of separation from most admixed materials by some process of elutriation, or water concentration, or, in arid regions, by dry blowing. The coarser particles are readily picked out, but the finer are usually admixed with heavy ...

Gold | Geoscience Australia
Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.
Alluvial Placer Gold Machine
To summarize, we can separate gold ore into two categories: alluvial /placer gold and rock gold.
