What are the chemical and physical separation methods used

What happens in most modern gold mining operations is a combination of physical and chemical separation to recover the gold. The ore is ground to a certain size and passed through a stage of physical separation. When the coarse fraction of the gold is separated the fine gold is recovered by chemical means.
