What are the chemical or physical separation methods

There are two separate processes to refining gold: First the raw/impure gold is melted down and kept molten while being subjected to chlorine gas. This forces most of the base metals and silver to separate. The gold is then poured into molds to make anodes, and put into a solution that pulls gold molecules to the cathode.
