(There is also a mineral known as "Amalgam", which is a composed of silver and mercury (Ag,Hg), but the common term of amalgam denotes a mixture of mercury and any other metal.) Amalgams are used to extract precious metals from their ore. Ingested mercury and mercury mixtures are health hazards, and be lethal if a large amount is ingested.
Mercury processing: Mercury processing, preparation of the ore for use in various products. Mercury (Hg) has a unique combination of physical properties. Its low melting point (−38.87 °C [−38 °F]) and boiling point (356.9 °C [674 °F]), high specific gravity (13.5 grams per …
Beginning in 1558, with the invention of the patio process to extract silver from ore using mercury, mercury became an essential resource in the economy of Spain and its American colonies. Mercury was used to extract silver from the lucrative mines in New Spain and Peru.
In 1700, New Spain's silver production hovered around 5 million pesos annually. By the 1780s, the figure had quadrupled. As early as 1600, silver ore, bullion, and coins constituted some 80 percent of New Spain's exports, making it far and away the largest and most important industry in Spain's wealthiest and most important colony.
The ore containing the precious metals should be ground fine enough to allow the maximum exposure of the gold or silver surface to the mercury (usually between 100 mesh and 325 mesh). Often, water is used as the ore is mixed with water to help disperse the ore and to promote a better precious metal to mercury interface.
Silver-mercury amalgams are important in dentistry, and gold-mercury amalgam is used in the extraction of gold from ore. Dentistry has used alloys of mercury with metals such as silver, copper, indium, tin and zinc.
release from taconite processing on the iron range. Hg(II) in ore concentrate is converted to Hg(0) during the firing of pellets and released to the atmosphere in stack emissions. Emission factors reflect primary distribution of mercury in the ore body, and generally

Methylmercury and other organic mercury compounds are formed when mercury combines with carbon. Microscopic organisms convert mercury into methylmercury, which is the most common organic mercury compound found in the environment. Elemental or metallic mercury is a shiny, silver-white metal and is liquid at room temperature.
