The act of mining Brazilian Gold in the Amazon, beginning in the 1690s, has profoundly transformed the economy of Brazil and other surrounding countries. In the late 17th century amid a search for indigenous peoples to use in the slave trade, Portuguese colonists began to recognize the abundance of gold in the Amazon and catalyzed what would become the longest gold rush in history.
In 2017, after four decades of using mercury, the miners at Gualconda fully transitioned their gold ore processing away from mercury. Now, the only obstacle standing in the way of their mercuryfree dream is the remediation of the original processing site.

A major source of air pollution from mercury, artisanal and smallscale gold mining releases approximately 400 metric tons of airborne elemental mercury each year. Located in over 55 countries, small scale gold buying and refining facilities (commonly referred to as Gold Shops) are an important part of this production process, and are a major cause of air pollution from mercury.
In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold 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 article notes the neglect of many major international donor projects on artisanal mining and mercury abatement to assess many alternative methods of recovering gold, and often the lack of a
The Clean Mining gold recovery process, developed by Australias CSIRO, replaces cyanide and mercury with a safer, less hazardous chemical reagent. This alternative gold recovery solution is nontoxic and dissolves fine gold out of ores into a solution, which can then be recovered through further processing.
