effect of small scale mining on birim river

Small scale gold mining, popularly called " galamsy" in Ghana and other developing countries, is seen as a source of subsistence and a determinant of the environmental degradation [1]. In Ghana, small scale gold mining is set to be responsible for about 5% of the annual gold production.

The calculation of the Hg Enrichment Factor (EF) using Sc as refractory element confirms high enrichments around active sites of gold mining being proportional to the density of miners and the duration of mining activities. The Hg spatial distribution reveals a very local contamination and a limited downstream dispersion of the contaminant.

Alluvial Artisanal and Small-Scale Mining in A River

Artisanal and small-scale mining is a significant economic sector in Rwanda. Mining activities often use a watercourse, in which secondary extraction takes place and minerals are washed. Mining thus greatly affects the geomorphological conditions in the area. The aim of this paper is a digest of environmental impacts of alluvial artisanal and small-scale mining with a focus on anthropogenic
