chemical and physical separation methods in gold

chemical and physical separation of gold. What are the chemical and physical separation methods used. The gravity separation process is a method of deferentially separate ore according to mineral density. So it need not to use chemical. For chemical physical separation method, we usually use flotation process, leaching method to do gold mining.
