Mining Free Full-Text Environmental Impacts of Gold Mining
Gold mining has serious negative environmental impacts, especially due to pollution emanating from tailings storage facilities (TSFs, tailings dams, slimes dams). The most important forms of pollution from TSFs are acid mine drainage (AMD) and high levels of potentially toxic elements (PTEs). AMD arises from the high levels of pyrite in the 2. Background on the artisanal mining/farming nexus, research context, and methods. The upsurge of ASGM across sub-Saharan Africa involving a wide variety of ‘labour intensive activities without mechanisation’ (Weng et al., Citation 2015) has led to wide-ranging debates about the ways in which poverty-driven gold mining fits or remains invisible Artisanal Gold Mining and Farming: Livelihood Linkages and Labour

Multivariate studies and heavy metal pollution in soil from gold mining
Abstract. Mining generates large volumes of waste, which if not regulated can release toxic metals, causing widespread environmental contamination. This study focused on heavy metal contamination in topsoil within a mining area at Nangodi in the Northern Region of Ghana. A total of 24 soil samples were collected from the study area Africa's gold mine production was 522,000 kilograms/1,148,400 pounds in 2005, which was a decrease of 14% compared with that of 2000. Production was considerably less than that of 1990 because of the long-term decline in South African production. From 1990 to 2005, Africa's share of world gold mine production decreased from 32% to about 21%.Mineral industry of Africa
