Artisanal mining

Artisanal mining in the Barberton region produces relatively large nuggets in reasonably profitable mining ventures. Formal mines, such as Agnes, Fairview, Consort, and Barbrook, are relative small, and artisanal mining is growing in the region. Since artisanal mining is illegal in South Africa, it is difficult to estimate its economic value.

Crushing Ore for Gold Veins

For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

Environmental Impacts of Gold Mining

Artisanal, or small-scale, gold miners are tearing down the forest to access the rich gold deposits beneath. One study found that deforestation rates in the Madre de Dios region of the Peruvian Amazon have increased six-fold due to gold mining. Gold mining is also responsible for releasing large amounts of mercury into the Amazon's air and water.
