The use of mercury to recover gold probably dates back to the Romans this was written about in De re Metallica by Georgius Agricola during the 16th century. In this book the recovery of gold using mercury was also described.

Likely the Best Fine Gold Recovery Equipment based on the enhanced centrifugal forces, like the Falcon Concentrator, has a maximum capacity of 150 t/ concentrator has proven effective in various minerals sectors link gold, Cu, Sn, Coal, Iron ore, Ag, Heavy mineral and most significantly tantalum where Falcon has achieved excellent results.

Watch how the GOLDROP easily separates all the gold from this Snake River Paydirt. The Magnet Sluice lined with magnetite again catches the miniscule loss exiting the GOLDROP as well as a high grade gold rich ore. Using a SpinItOff to remove the magnetite, the Gold Claw pan roughs off the overburden mineral to finish the fine gold recovery.
In the 1800s the use of mercury to extract gold from ore (called Amalgamation) was the most commonly used method by small scale prospectors for this purpose. It has been a highly controversial method of extraction to say the least because of both the physical and environmental health risks that mercury poses. Individual prospectors will []

Currently, around 75% of gold extracted from ore is processed using the hazardous chemicals of cyanide or mercury, which are toxic to humans and the environment. These chemicals are often contained in large storage tanks and, once used, expelled into large tailing dams that can potentially leach into the local surrounds or, worse, burst as weve seen in recent years in Brazil and Canada.

New Gold Recoverys system recovers approximately 90% of the gold present per ton of concentrate, a fact which has been verified by Global Mineral Research (GMR), a worldrenowned thirdparty metallurgical research lab. To be clear, these results are more than 220% the global average in gold recovery.
#0183;#32;Many artisanal and smallscale miners are achieving high rates of gold recovery without mercury, benefiting their health, the health of their communities, and the environment. On this page, we summarize some of the techniques in mercuryfree artisanal and smallscale gold mining.
