Emerging mercury mitigation solutions for artisanal small-scale gold

Over 15 million people are involved in artisanal small-scale gold mining (ASGM) globally. Often, ASGM includes smelters that use mercury to extract gold. If mishandled, these actions may cause adverse health effects for smelters and their surrounding communities. There are multiple tools to reduce health risks while Four main categories of gold mines have been distinguished: (i) illegal artisanal and small-scale mining, which can involve the exploitation of both primary (hereafter called i-ASMp) or secondary (i-ASMs) gold deposits; (ii) legal artisanal and small-scale mining (ASM); (iii) legal medium-scale mining, in which gold can be recovered Sustainability Free Full-Text Territorial Mining Scenarios for

llicit Financial Flows and Con ict in Artisanal and Small- Scale Gold

Artisanal and small-scale mining (ASM) is an essential component of West African economies. Millions of people within the region depend on it, either directly or indirectly, for their livelihoods, and it is responsible for a significant proportion of the region’s mineral and metal production.Since the rise of the gold price in 2000, artisanal and small-scale gold mining (ASGM) is a growing economic activity in developing countries. It represents a source of income for several millions of people in West Africa. Exploitation techniques have evolved from traditional gold panning to mechanization and use of chemical products Artisanal Exploitation of Mineral Resources: Remote Sensing

Small-scale miners in Ghana, PC: Francis Carmine

And at the height of the gold rush it was estimated that billions of yuan were being sent from Ghana to China—far more than the Ghanaian governmental revenue (He 2013). The sudden influx of Chinese miners, and the expansion of their small-scale mining operations, was facilitated throughArtisanal and small-scale gold mining is a widespread activity in the Ivorian territory, more especially in the center of the country (Ahoussi et al., 2020; Daï-Bi et al., 2020; Ouattara et al., 2021). In view of the strong enthusiasm that these activities arouse, they may appear to be lucrative and have many negative impacts.Analysis of the Spatio-Temporal Evolution of Artisanal and Small-Scale

Sustainability Free Full-Text Potential Uses of Artisanal Gold

Due to the high global gold demand, the gold mining industry has recently emerged to have great potential, but most of this is carried out by individuals or cooperatives (artisanal small-scale miners) [5,6]. The gold mine tailings produced by small-scale miners are often dumped in designated tailing ponds with minimal treatment [5,7,8].1 Introduction. Artisanal small-scale mining (ASM) is a traditional type of mining that occurs in over 80 countries around the world, involving 30 million people (Tuokuu et al., 2020).The sector generates revenues for governments (Owusu et al., 2019), reduces rural poverty (Ofosu et al., 2020), creates employment for an unskilled workforce Frontiers Polluting our rivers in search of gold: how sustainable

Mapping the Reality of Hg-Free Artisanal Small-Scale Gold Mining

Artisanal gold mining (AGM) is a very important topic, of which the environmental and social impact has been widely studied. However, there are few studies on operational efficiency, financial analysis, and the lack of mine planning. The purpose of this work was to investigate whether AGM operation without mercury is sustainable. The This report is one of three synthesis documents produced via an integrated assessment (IA) that aims to increase understanding of artisanal and small-scale gold mining (ASGM) in Ghana. Given the complexities surrounding ASGM, an IA framework was utilized to analyze economic, social, health, and environmental data, and co-develop Integrated Assessment of Artisanal and Small-Scale Gold Mining

IJERPH Special Issue : Artisanal and Small-Scale Gold Mining

Dear colleagues, Artisanal and small-scale gold mining (ASGM) activity has been undertaken in developing countries for socio-economic reasons; however, it accounts for the largest anthropogenic source of mercury emission, at over 700 tonnes into the atmosphere and an additional approximately 800 tonnes into land and water The rapid growth of artificially constructed mining camps has negatively impacted the camps’ surrounding environment and the informal communities that have developed inside the camps. However, artisanal and small-scale gold mining (ASGM) is generally informal, illegal, and unregulated; thus, transformations of the mining activities Detection of Artisanal and Small-Scale Gold Mining Activities

Integrated Assessment of Artisanal and Small-Scale

This article is one of three synthesis reports resulting from an integrated assessment (IA) of artisanal and small-scale gold mining (ASGM) in Ghana. Given the complexities that involve multiple drivers Artisanal and small-scale gold mining (ASGM) is a significant source of gold production globally despite the sector being informal and illegal. The rapid increase in the number of roving mining camps has negatively impacted the surrounding environment; however, the formation and transformation of roving mining camps have not been well Investigation of Long-Term Roving Artisanal and Small-Scale Gold Mining

Sustainability of the Artisanal and Small-Scale Gold Mining in

The aim of this work is to explain the concepts of sustainability with respect to small artisanal gold mining. For this, a qualitative approach with a descriptive scope was used, for which the bibliographic review technique was conducted. In this sense, articles, theses, books and institutional documents, and any contribution related to the research involved in gold mining including illegal panning for gold along river beds. However, there is a considerable amount of mining on a small scale for other minerais such as beryl, chromite, vermiculite, agate and clay. Small scale miners are supported by well established government and non-government administrative structures which offerSmall-Scale LYRASIS

Heavy Metals in the Soils of Placer Small-Scale Gold Mining Sites

Small-scale gold mining plays an important role in Myanmar's gold production. The CEIC database reported that gold production in Myanmar was 1692 kg in 2015 and 1700 kg in 2016. 25 However, there have been few studies of the impacts of gold mining in Myanmar. The aim of the present study was to investigate As, Cd, Hg and Pb Artisanal and small-scale gold mining (ASGM) has many definitions depending on the context. However, the common theme that characterises gold mining operations that fall within this category is that they make use of rudimentary methods to mine and process gold.

High Environmental Radioactivity in Artisanal and Small-Scale Gold

The radioactivity associated with artisanal and small-scale gold mining activities (ASM) carried out along the Ulindi River, in the eastern Democratic Republic of the Congo, was evaluated by gamma-ray spectrometry and inductively coupled plasma–mass spectrometry of soil and sediment samples. The results revealed that activity small–scale mining represents a significant proportion of mining production in the continent, and also of the labour force employed in mineral and metal extraction. It is also important to note that small–scale mining is not a recent phenomenon and that it is a universal activity, that has appearedRecursos naturales e infraestructura
