In small-scale gold mining, the raw ore containing only about 1-100 g Au per ton has to be concentrated into marketable products containing at least about 90 % Au. The requisite
Cyanide is the current large-scale mining industry standard for gold extraction from milled ore, but can it also serve as a responsible mercury-free alternative for artisanal & small-scale gold mining? Explore the issue in this report.
Colombia is a small player in gold, with only ∼2 % of global annual production (World Population Review, n.d.). Yet gold mining supports hundreds of communities, with profound …
In Colombia, a consumption of 193 tons of Hg per year was established for mining purposes, of which 105 tons were concentrated in legal operations and 88 in operations outside the law (MME, 2014).The problem of pollution and environmental degradation associated with gold mining activities using the amalgamation process has been extensively studied, mainly in …
In Colombia, an estimated 70 percent of gold production comes from artisanal and small scale miners (ASGM), and the department of Antioquia is the second-largest department in ASGM in Colombia, with over 1,300 small scale gold mines identified in 2012 ().Small scale and artisanal miners face significant challenges in their livelihoods, including serious health …
Several artisanal and small-scale gold mining (ASGM) sites in Colombia were located and sampled. At each ASGM site, tailings samples were collected and analyzed.
As supply-chain certification may require formalization, we explore miners' motivations for and barriers to formalization within a choice experiment in two Community Councils in Afro …
Artisanal and small-scale gold mining (ASGM) is the largest anthropogenic source of mercury emissions. Approximately 200 metric tons of elemental mercury are commercialized every year for ASGM purposes; this accounts for >30 % of the total mercury used in industrial applications (Gallo Corredor et al., 2021; Yoshimura et al., 2021).Due to the rudimentary gold …

The aim of this study was, first of all, to associate the mercury (Hg) concentrations and respiratory functions of the gold miners in the artisanal small-scale gold mining (ASGM) environment in San Martín de Loba, Colombia. We carried out a cross-sectional study using a survey whereby we collected basic demographic information, occupational medical history, and …
ABSTRACT. People making a living in rural Antioquia, Colombia, find themselves in a double bind: they require a healthy environment to farm and grow food, but many turn to artisanal and small-scale gold mining (ASGM) to supplement their incomes.
Likewise, this documentation contributed to the delimiting aspects that allowed a contrast between the proposed definitions and small artisanal mining in the Northeast Antioquia region in Colombia. Based on the reviewed sources, different needs were recognized in artisanal small-scale gold mining in Northeast Antioquia that still need action.
and Development (OECD) report on gold mining in Colombia, small-scale informal miners are vulnerable to the influence of illegal armed groups. (Massé & Munevar 2016) There is already an existing relationship between informal miners and paramilitary groups, who are gaining control over the gold mining economy (Bargent 2013).
Small-scale and artisanal gold mining (ASGM) in Colombia is an activitythat, besides being highly affected by and connected to illegal activities, has a significant negative environmental impact. About 80 percent of the gold produced in the country comes from artisanal and small-scale miners. According to a sector
Artisanal and small-scale gold mining (ASGM) in the Amazonian countries has undergone important technological improvements in recent decades. Nevertheless, this type of mining is largely associated with the use of rudimentary, low-tech and often manual methods, and inefficient gold recovery (Hilson and Van Der Vorst, 2002, Veiga et al., 2014a).

1. Introduction. Attributed with releasing 1220 metric tons of mercury in 2015 alone, artisanal and small-scale gold mining (ASGM) has gained international attention as the largest anthropogenic source of mercury pollution in the world (UN Environment, 2019).ASGM is also responsible for the release of lead, arsenic, cadmium, copper, and a wide array of additional …
