1. Introduction. Small-scale mining has played an increasingly important role for communities that depend on this activity worldwide. Buxton [] estimates that small-scale mining employs 20 to 30 million people in over 80 countries, and that this sector is responsible for 15 to 20% of the global production of minerals and metals.Villegas et al.[] report that small-scale …

Artisanal and small-scale mining (ASM) is an important source of livelihood for millions of people in Sub-Saharan Africa (SSA), though it is small in its contribution to the total mineral production but employs a larger number of people in rural communities than large-scale mining activities do (Hilson and McQuilken 2014).It is reported that over 25 million people in …
A primary goal of prevention efforts with mining families is to educate them about exposure risks, to provide access to affordable safety and mining equipment, and to practice …
Abstract: Small vertical shafts can play a significant role in small scale mining as they represent a quick and efficient method to gain access to veins located 20 to 50 m below surface. Historically, in central Africa, colonials effectively used
Introduction. Small-scale gold mining has served as a substantial means of subsistence for rural communities worldwide [].Research indicates that around 15 million people have engaged in gold mining as a result of the widespread desire to become wealthy quickly [], [].Artisanal gold extraction has played a substantial role in the economies of many developing countries [], [].
The aim of this paper is a digest of environmental impacts of alluvial artisanal and small-scale mining with a focus on anthropogenic influences on topography with regard to the methods used in ...
The widespread prevalence of illegal Artisanal Small-Scale Mining has raised significant concerns about its environmental and health impacts. This study investigates the effects of two mining methods (alluvial and chamfi) on soil physical, chemical, and microbial properties four years after mining in three municipalities of the Western Region of Ghana.
Artisanal and small-scale mining (ASM) activities have contributed, in most cases, to the rural development of some African countries. Practically, these activities have influenced the ...
• Enactment of specific small-scale mining laws and regulations, including a separate set of safety rules. • Establishment of small-scale mining unit within the Mines and Geoscience Bureau to support and regulate the sector. • Decentralization of the issue and control of small-scale mining permits and licences through local government units.
of mining licenses? The stipulation that the artisanal licence cannot be renewed after the two years' required duration is problematic. Due to a number of constraints, most of the artisanal mining license holders cannot fully meet the requirements for a special small-scale mining license and will be left unemployed.
The literature about SSM in the Global North is limited to research of: 'modern small-scale mining' in medium income nations in Europe (Moore et al., 2021; Sidorenko et al., 2020; Sydd et al., 2022, 2023); technological innovations for mechanically separating fine gold from Yukon ores (Clarkson, 1994); how technology might be diffused in the Global South …
The open cast method of small-scale mineral mining employing equipment/machinery such as bulldozers, dredging boats, pickaxes and shovels strip the land bare of vegetation and destroys soil fertility. As observed by Aryee et al. (2003), land degradation is a common phenomenon at many uncontrolled, unmonitored small-scale mining sites. ...
Emerging evidence indicate that artisanal and small scale gold mining related mercury contamination in Africa is contributing to serious health and ecological impacts and has raised concern among ... as the borax method and the gravitation methods which proved to be equally 5. efficient when used as demonstrations during the Global Mercury Project
Artisanal mining is basic mining characterized by manually intensive work methods utilizing primitive or simple equipment and conducted by individuals or small groups exploiting deposits.
In recent decades, gold mining expanded from its historical core (South Africa, the United States, Canada, Australia, and Russia) into a wide range of new gold mining regions, many of them located in the global South (Verbrugge and Geenen, 2020).In addition to the expansion of large-scale industrial mining, many of these regions have witnessed a notable …
The government of Ghana responding to public outcry against the negative effects of "galamsey", placed a ban on illegal small-scale mining activities in March 2017.
