In order for mercury to amalgamate with gold the two metals must be able to come in contact with each other. If either the mercury or the gold has a coat of anything on it you will never get it to amalgamate. It''s like the gold is enclosed in little plastic bags. They just can''t get together.

Use and Loss of Mercury in Gold Mining . To enhance gold recovery from hydraulic mining, hundreds of pounds of liquid mercury (several 76lb flasks) were added to riffles and troughs in a typical sluice. The high density of mercury allowed gold and goldmercury amalgam to sink while sand and gravel passed over the mercury and through the sluice.
