Background: Mercury (Hg) is used in gold mining to extract gold from ore by forming "amalgam"—a mixture composed of approximately equal parts mercury and gold. Approximately 15 million people, including approximately 3 million women and children, participate in artisanal small-scale gold mining (ASGM) in developing …
Abstract. Land use conflicts are becoming increasingly apparent from local to global scales. Surface gold mining is an extreme source of such a conflict, but mining impacts on local livelihoods often remain unclear. Our goal here was to assess land cover change due to gold surface mining in Western Ghana, one of the world's leading gold ...

Regular drills and training sessions are conducted to educate miners on emergency procedures and promote a quick response in crisis situations. ... Mining Environmental …
mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic substance, coal, is often discussed as a mineral as well.)

The mine was privatised and awarded to Midroc Ethiopia in 1997. A mining license was awarded and a new company – Midroc Legadembi Gold Mine Share Company (Minroc Gold) commenced production in August 1998. Average yearly production totals 4.5 t. The Lega Dembi deposit is the largest gold producer in Ethiopia.
A risk assessment study of MEL for their categorization and prioritization in gold-mining areas of Macuchi, Tenguel-Ponce Enriquez, and the Puyango River Basin in Ecuador, conducted by Salgado-Almeida et al., revealed that the impacts are mainly associated with artisanal and small-scale gold mining.

This study interrogates the impacts of mining at Connemara Gold Mine on the environment and rural livelihoods for surrounding communities the mine. While we acknowledge that mining is a very ...
The impacts and social context for artisanal and small-scale gold mining (ASGM) are very different from those for large-scale mining (LSM) operations. LSM requires significant upfront capital investment well before production begins or any returns are realised, as well as further sustaining investment, often over long periods.
mining projects and artisanal mining, driven by sustained high gold prices. Ore from small-scale and artisanal gold mining is processed in numerous small mills (entables) around Marmato, which impact surface water quality through the discharge of milled waste rock slurry, highly alkaline cyanide-treated effluent, and high dissolved metal loads.
1. Introduction. Recent global estimates assert that 14–19 million people are employed in artisanal and small-scale gold mining (ASGM) [].In Zimbabwe, ASGM is one of the informal sectors with a key economic role as it serves as a fundamental livelihood source [].This role has recently expanded as a result of persistent droughts and …
The study investigated the role of small-scale gold mining in promoting sustainable livelihoods among local communities in Kadoma District of Zimbabwe. The sustainability of small-scale gold mining is a contentious issue given the level of environmental degradation and the disruption of social relations taking place in the district.
The main hypothesis is that sites of artisanal gold mining activities are characterized by higher concentrations of toxic metals than the farmland and forest sites. Although the study area has a long history of gold mining (which probably commenced around 1940), the activities are up till date artisanal (Makinde, Oluyemi, & Olabanji, …
Focus group questions were designed to document the socio-cultural impacts of the Spill. This paper: (1) outlines the partnerships and approvals; (2) describes focus group design, training, data collection and analysis; and (3) reflects on the use of a culturally anchored approach in Indigenous, specifically Diné-centered research.
The Lom River draining the gold mining site was turbid (117–510 NTU) ( Table 1 and Figure 4 f). Tu values exceeded the limits of 5 and 4 NTU set by the World Health Organization, 2011, World Health Organization, 2017. 43.7% of the water samples had a turbidity higher than the total mean value (203.3 NTU).
The report also identifies reforms to revitalize federal support for research into advanced, lower-impact mining and exploration technologies and methods, workforce development, and the need for increased resources to address the legacy of abandoned and unreclaimed hardrock mining sites that continue to pollute land and water …
This paper evaluates the impact of gold mining activity on surface water quality in the locality of Batouri (East, Cameroon). Water samples were collected from five separate points.

In November, mining minister Winston Chitando announced that the government will force companies to develop these assets as part of a 'use it or lose it' policy, its latest attempt to remove inefficiencies from and stimulate growth in the mining sector. The policy builds on similar initiatives deployed in the gold mining sector, and is …
Mining contributes 11% of gross capital creation but also 16% of total direct foreign investment in South Africa. Despite accounting for just 0.3 percent of taxpayers, the sector was liable for 6 percent of the tax imposed in 2014. Although quarrying employs about 500,000 people, it accounts for barely 5% of the country's employment.
