Dissertations / Theses: 'Artisanal and small scale gold mining
Abstract: This thesis determines that over four hundred thousand artisanal and small-scale gold miners all over China systematically use amalgamation and release approximately 240 tonnes of mercury per annum. Artisanal and small-scale gold mining (ASGM) is one of the largest sources of mercury pollution in China.On the African continent, in Kenya (Odumo et al., 2018), environmental degradation occurs in the face of Au mining, in an artisanal manner and with the use of Arsenic (As), in the districts ofArtisanal gold-mining in a rural environment: Land

The history and economics of gold mining in China
The global low-sulfide quartz-vein gold-deposit model was produced in 1986. There have been many significant discoveries since, particularly in China (Zhang et al. 2015), and many of the depositsExploration activities on the rise. The overall gold exploration budget reached US$6.2b in 2021, up 42% YOY and the highest growth since 2011. 4 This is primarily due to high cash at disposal for miners, with record-high gold prices averaging US$1,798 per ounce (oz) in 2021, 21% higher than the usual incentive price of How gold miners can build long-term competitiveness EY US
