![]() The process is controversial because of the extreme toxicity of mercury to humans, but it has been used for centuries. ![]() The mercury vapor is captured by distillation. The amalgam is then heated to 816☌ (1500☏) to make the mercury boil off, leaving only the silver or gold behind. Water is sometimes used to promote the process. 2), which is then separated from the waste ore. The mercury combines with the silver or gold, forming an amalgam (Fig. In amalgamation, the ore containing silver or gold is ground up and then mercury is mixed with it. Mercury belongs to the 6 th period of the periodic table between gold (Au) and titanium (Ti). ![]() Let us predict the period of Hg in the periodic table. Interestingly, mercury dissolves gold, silver and most other metal in a property known as amalgamation, which makes mercury an important tool in the mining of both precious metals. A period is the horizontal row of chemical elements which possess almost similar properties. Mercury’s symbol (Hg) is derived from its Greek name hydrargyrum, which translates to “silver water” or “liquid silver.” Compared to other metals, mercury is an ineffective conductor of heat but a mild conductor of electricity. Mercury is used in thermometers, barometers, and other laboratory equipment however. The only other element in the periodic table that shares this attribute is bromine (Br). Mercury is one of the three elements that are liquid at room temperature. Mercury is a dense, shiny, silvery-colored metal whose most unique characteristic is that it is a liquid at room temperature (Fig.
