Amalgamation is a concentrating process in which metallic gold or silver or an alloy of the two is mixed with mercury either in a amalgamation drum or on a amalgamation table where the precious metal bonds with the mercury to form the metal laden mercury AMALGAM and the waste barren ore pulp are caused to travel different paths to effect separation
Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury
Jul 22 2019 · A mercurygold amalgam then is formed because gold will dissolve in the mercury while other impurities will not The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury leaving behind the gold This process does not result in gold that is 100 pure but it does eliminate the bulk of the impurities
