Industry: Artisanal Mining

In the Manica District of Mozambique, more than 10,000 people are directly and indirectly involved in artisanal (small-scale) gold mining activities (garimpagem) as their main source of income. Most of “garimpeiros” (artisanal miners) use mercury to extract gold form the mineral ore; the amalgation process recovers very little of that mercury, which pollutes the nearby environment. The majority of the mercury used pollutes local waterways and soil as well as threatens the livelihood of plant and animal species in the area. Mercury amalgamation results in the discharge of an estimated 1000 tons of mercury per annum, representing about 30 percent of the world’s anthropogenic mercury releases.
