Use and Loss of Mercury in Gold Mining . To enhance gold recovery from hydraulic mining, hundreds of pounds of liquid mercury (several 76-lb flasks) were added to riffles and troughs in a typical sluice. The high density of mercury allowed gold and gold-mercury amalgam to sink while sand and gravel passed over the mercury and through the sluice.Jul 25, 2017 Hard Rock miners around the world have historically recovered as little as 30 of their free gold using mercury amalgamation. The iCON process is being used to scavenge reprocess old tails without using mercury. These miners are now recovering gold reprocessing tails with iCON than the original miners recovered.
