2016-11-1 Artisanal and small-scale gold mining (ASGM) occurs in over 70 countries (Telmer and Veiga, 2009) and is the largest anthropogenic source of mercury (Hg) in the environment . In the Brazilian Amazon alone, 2000–3000 tons of Hg has been released into the environment since the 1970s (Malm, 1998, Pfeiffer et al., 1993).

2018-1-3 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.

This paper provides an overview of the initiatives that have been undertaken by the Ghanaian government to promote more sustainable development in resident small-scale gold mining operations, and recommends a series of strategies for perpetuating a pattern of continued improvement. Since the passing of the ‘Small Scale Gold Mining Law’ (PNDCL 218) in 1989, which effectively legalized small ...

2019-2-1 Gold mining in Ghana occurs in two main forms, large-scale mining (LSM), involving heavy mechanization and artisanal and small-scale mining (ASM), typically involving simple hand tools such as pickaxes and shovels for digging gold-bearing materials. Artisanal and small-scale mining is the oldest form of mining in the country and was practiced ...

Background: To determine the potential risk factors for injury, estimate the annual injury rate and examine the safety perceptions, and use of personal protective equipment among small-scale gold miners in Ghana. Methods: A cross-sectional survey was carried out with 494 small-scale gold miners from four major mining districts in Ghana.

2018-5-11 The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity.1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
