Mercury processing Extraction and refining Britannica
The pyrometallurgical extraction of mercury from its ore is essentially a distillation process. When heat is applied to the sulfide ore in the presence of air,bines with the sulfur to form sulfur dioxide, and the metal is liberated at a temperature above its boiling point.
mercury to gold process
In many countries, elemental mercury is used in artisanal and small scale gold mining. Mercury is mixed with gold containing materials, forming a mercury gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Mercury Usage in Gold Mining and Why It Is a Problem
22/07/2019· How Mercury Is Used in Gold Mining First, mercury is mixed with the materials containing gold. A mercury gold 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.

OverviewConcentrationHistoryTypes of oreLeachingRefractory gold processesGold smeltingGold refining and parting
Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smeltedto for
How Is Mercury Used to Purify Gold? Sciencing
Gold dissolves in mercury similar to the way salt dissolves in water. Miners submerged their ore in mercury, which would take on the gold but not the other impurities. The mixture of mercury and gold would then be recollected and heated until the mercury boiled away.
Amalgamation: Using Mercury to capture fine gold, retort
Mercury and free gold can be brought together in a number of ways, but to mix well, both the mercury and gold must be clean. Coatings, especially those which are oily in nature, prevent the two from mixing. In the old days, miners placed mercury in the riffles of sluices, dry washers, and similar devices to aid capture of fine gold. At the base of most of the old stamp mills was a plate
