The most common practice was to pass a slurry of crushed gold ore over large copper plates that had been coated with mercury. In the case of silver, a slurry mix of crushed silver ore was run through metal pans containing mercury. (2) the process by which mercury is alloyed with some other metal to produce an amalgam. Used at one time for the extraction of gold and silver from pulverized ores.
