Leaching gold with cassava: An option to eliminate mercury use in artisanal gold mining

Updated: 6 days ago

Mercury pollution from artisanal gold mining causes severe environmental and health problems, especially to operators and people living around the processing facilities. Over 2000 tonnes/a of mercury is released to the environment by the artisanal miners which is the largest man-made source of mercury pollution.

“We propose to use a solution extracted from plants, bitter cassava, as a gold leaching lixiviant for the first time in the history of the mining industry.”

Marcello M. Veiga, Ph.D.

Approximately 18 - 20 million impoverished artisanal and small-scale gold (ASG) miners all largely having undiagnosed mercury poisonings in ~ 80 countries dangerously toil daily to produce ~20% of the world’s gold supply used for our jewellery, our iPads, our iPhones, computers, and other e-devices.

This includes 4.5 million women and 600,000 children under the age of 15 all exposed to mercury, a deadly neurotoxin.

Collectively they are responsible for the annual discharge of 2,000 tonnes of mercury to our biosphere documented in 2021 by Oxford University earth scientists to stay airborne up to one year.
