Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex It is the most commonly used leaching process for gold extraction...

How mercury is made

Mercury readily forms alloys with other metals, and this makes it useful in processing gold and silver Much of the impetus to develop mercury ore deposits in the United States came after the discovery of gold and silver in California and other western states in the 1800s...

Artisanal and Small

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...

The Borax Method of Gold Extraction for Small

Borax was added to milled ore to reduce the melting point of gold to a level accessible to SSM The amount of gold captured, and the amount of mercury released into the environment, was compared to two common amalgamation methods: whole ore and heavy metal Discussion The borax method appears to capture more gold, as well as eliminate the use of...

How gold is made

Two other methods of gold refining are amalgamotion and smelting In amalgamation, the gold ore is dissolved in solution and passed over mercury-covered plates to form a gold/mercury amalgam When the amalgam is heated, the mercury boils off as a gas and leaves behind the gold...

Mercury Amalgamation

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...
