    Jul 28, 2018 The effects of small-scale gold mining activities on heavy metal levels in groundwater were determined for the Lower Pra Basin of Ghana. Sixty five boreholes in 45 communities were analysed between January 2012 and April 2012 for the dry season and June and October 2012 for the wet season. The test for significance and the use of cluster analysis, a multivariate approach, clearly

    Background: The use of mercury in artisanal and small-scale gold mining has negative effects on human health and the environment. In Suriname, the current gold rush resulted in estimated mercury emissions up to 63t per year. To reduce the use of mercury and the subsequent health impact to gold miners and local inhabitants, knowledge and awareness in the community should be increased

    Apr 17, 2013 Mining also requires large amounts of land that could otherwise be used for agricultural production. This sets up a direct competition with small-scale agriculture for control and use of land. In some countries such as Ghana, farmers displaced by mining projects turn to small-scale mining as a replacement livelihood. This can perpetuate a cycle

It is estimated that over 10 million people worldwide are directly engaged in small-scale mining activities, with another 80 to 100 million people directly or indirectly dependent on the production from these activities

    Aug 16, 2018 Small-scale mining and land-based fish processing were important industries historically within PWS, but these were few and scattered (Lethcoe and Lethcoe, 1994). Contaminant effects of these activities on shorelines were attenuated by the 1964 Great Alaska Earthquake, which uplifted most shorelines within the spill trajectory from 1 to 10 m into the supratidal (the zone immediately above the

    There are approximately 100 million artisanal miners globally. Artisanal and small-scale production supply accounts for 80% of global sapphire, 20% of gold mining and up to 20% of diamond mining. It is widespread in developing countries in Africa, Asia, Oceania, and Central and South America. Though the informal nature and on the whole un-mechanized operation generally results in low productivity, the

    illegal small scale mining in Ghana might be a resource curse rather than a blessing. Much has been written of late about the illegal small scale mining in Ghana and the negative impact it is having on agriculture specifically cocoa production. However, this perceived negative impact should not be taken for granted because this has
