Any amalgamated metals such as gold will be left behind in the retort. Actually, in order ...
It is filtered through a special 1mu Oro Mercury pressure filter, where the liquid Mercury is separated from the Gold amalgam. The Gold amalgam is 50/50 by weight Gold & Mercury. The amalgam is then placed into a Oro Mercury Retort, where the Mercury is safely retorted (vaporized) and re-condensed into a clean gold free liquid.
mercury binds to the flakes of gold and forms a solid mercury-gold amalgam. The amalgam is then heated to vaporize and capture the mercury in an enclosed retort oven, leaving the gold behind.

The distillation is performed at a very low temperature and heat applied very gradually, until 1,500 deg F is reached.. It usually takes 2 hours to retort the amalgam, once the 1500 deg F temperature is reached. DANGER! It should be noted that mercury is very poisonous to humans and many forms of life.
Apr 24, 2017· Mercury is a metal with special properties that give it a wide variety of applications. Most obviously, mercury is a liquid at room temperature and standard air pressure. It is this property that caused it to receive the name hydrargyrum, meaning "watery silver" in Greek, from which its symbol, Hg is derived. ...
Mercury was used in these facilities to remove gold by forming a mercury-gold amalgam. The gold was purified either by heating the amalgam in the open with a propane torch or by using a small retort. Methods: Thirty-eight workers participated in this study.
Gold-Mercury Amalgam ... Never try to distill (retort) Mercury in a glass retort, as it will shatter. ... If you do, a very slight drop in the temperature of the boiling Mercury will create a vacuum sufficient to suck water back through the system right onto the boiling Mercury.

Mercury has traditionally been used in medical apparatus, electrical devices, precision instruments and in conjunction with other elements to form compounds for industrial applications. Despite its widespread use, mercury is a highly toxic material that needs to be disposed of properly once it is removed from use.
When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam – an amalgam is simply an alloy of gold and mercury. The gold literally is dissolved into the mercury. This allows the collection of very small sized particles of gold. At the end of the operation the mercury and gold amalgam are ...
