The Mercury Problem in Artisanal and Small-Scale Gold …

Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated-often with a torch or over a stove-to distill the mercury and isolate the gold. Mercury release from tailings and vaporized mercury exceed ...

World emissions of mercury from artisanal and small …

We estimate mercury releases from artisanal and small scale gold mining (ASGM) based on available data about mercury and gold exports and imports by country and from field reports from the countries known to have active ASGM communities. The quality of the estimates ranges from reasonable to poor across the countries. This paper aims to give a first order estimate of the amount and location of ...

Economic feasibility of responsible small-scale gold …

15/08/2016· Artisanal mining (AM) activities are generally seen as a source of concern owing to their illegality and the environmental pollution that they cause, but in recent years it has been demonstrated that gold mining can be performed on a small-scale mining (SSM) in a responsible way outside of the artisanal dimension. A previous study by the same authors demonstrated how mineral resources and ...

mining in Ghana: identifying problems and possible solutions

Although small-scale gold-mining activity is respon-sible for triggering a number of often irreversible erosional and siltation processes, it is a now widely recognized fact that the most serious environ-mental problem in the industry is excessive mercury pollution. Metallic mercury (Hg) has long been the preferred leach reagent for gold processing in developing countries. In a process known ...

World emissions of mercury from artisanal and small …

We estimate that artisanal and small scale gold mining releases between 640 to 1350 Mg of mercury per annum into the environment, averaging 1000 Mg yr-1, from at least 70 countries. 350 Mg yr-1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr-1) are released into the hydrosphere (rivers, lakes, soils, tailings). However, a significant but unknown portion of the amount released into …
