Amalgamation Gold Extraction Process Introduced

Mercury Amalgamation Corrosion


The production of silver in South America increased significantly after 1555, when the Hg amalgamation process was introduced. This drastically reduced the use of firewood, which had become scarce around the mines, and made silver extraction profitable also in the abundant silver ores with a metal content lower than the ores worked in Europe.

Amalgamation Using Mercury To Capture Fine Gold Retort


Occasionally, the amalgamation process does not collect as much gold as anticipated. This type of result usually occurs when the formation of amalgam is inhibited due to poor contact between the gold and the mercury. This happens most commonly when the gold is very fine or when it is tarnished by a surface or film.

Mercury Amalgamation


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.
