Title Examining the inconsistency of mercury flow in post-Minamata Convention global trade concerning artisanal and small-scale gold mining activity Type
Year 2022 Publication Resources Conservation and Recycling Abbreviated Journal Resour. Conserv. Recycl.
Volume 185 Issue Pages 106461
Keywords Mercury; Minamata convention; Global trade; Artisanal and small-scale gold mining (ASGM)
Abstract In 2017, the Minamata Convention (MC) on mercury (Hg) control entered into force. However, whether the MC is effective and how it reshapes the global Hg flow remain unclear. In this study, we established a method to detect inconsistencies in data on global Hg trade, and calculated the gap between the demand and supply of Hg to the artisanal and small-scale gold mining (ASGM) sector (i.e., the largest source of Hg emissions globally) in 39 countries across four regions. According to our results, inconsistencies in statistical data concerning Hg for ASGM activities exist in both Africa and Central and South America. Asia showed a considerably lower amount of Hg applied to ASGM than apparent Hg consumption; nevertheless, the largest consumer of Hg was Asia, predomi-nantly China and India. Many countries in which ASGM is conducted are already MC parties; however, only few submitted their national action plans (NAPs) or have established/enforced specific laws to curb Hg use in ASGM. Analysis of Hg-related trade information suggests that in 2017, the trade of metallic Hg disappeared in some African and Central and South American countries, but new trade flows of goods with higher Hg content emerged. The method established in this study can support the search for countries implementing ASGM with hidden Hg use and flows, thereby contributing to the planning of further Hg control regulations. To enforce sound Hg management, the submission of NAPs should also be promoted in addition to the expansion of MC parties.

Title A review of gold production, mercury consumption, and emission in artisanal and small-scale gold mining (ASGM) Type
Year 2023 Publication Resources Policy Abbreviated Journal Resour. Policy
Volume 81 Issue Pages 103370
Keywords Illegal artisanal and small-scale gold mining (ASGM); Gold production; Mercury use; Mercury emission; Minamata convention (MC)
Abstract Artisanal and small-scale gold mining (ASGM) is one of the largest sources of Hg emissions and is critical for addressing the Hg problem. Due to scarce and punctual statistics provided by governments and agencies, there is almost no accurate data on ASGM production, Hg use, and emissions. In this study, we surveyed different ap-proaches to estimate ASGM production and collected data from different sources, including academic papers and technical reports. Globally, 380-870 tonnes of gold is produced by ASGM each year, with a median value of 520 tonnes. The Hg use in the ASGM sector was estimated to be 640-1000 tonnes each year, with a median value of 892 tonnes. Consequently, 248-838 tonnes of Hg are emitted from the ASGM sector each year, with a median value of 615 tonnes. However, significant discrepancies were found in the data calculated using different ap-proaches, particularly in countries where the estimates were large, such as China. To obtain a more accurate picture of global ASGM activities, a general estimation approach combining specific studies of dominant coun-tries is necessary. For better management of ASGM in the future, developing a solid baseline and comprehensive future projection scenarios and establishing international collaboration to construct guidance on ASGM are recommended.

Title Socio-technical study of small-scale gold mining in Suriname Type
Year 2017 Publication Journal Of Cleaner Production Abbreviated Journal J. Clean Prod.
Volume 144 Issue Pages 107-119
Keywords Artisanal mining; Suriname; Gold; Mercury
Abstract Small-scale gold mining is Suriname's main economic sector, producing about two thirds of the nation's gold. Despite this, the sector is only very loosely regulated and most small-scale mining activities are informal. Surinamese miners are only a minority: the majority are Brazilian migrants, who have no right to the land and therefore have to pay a percentage of their production for land use. This study reports the findings of a field mission to small-scale mines in the region of Brokopondo reservoir. We document the technical aspects of small-scale gold mining in Suriname and contextualize this technology to social issues to identify links with cultural, political and sociological factors. Our findings show that informality and insecurity lead to a mine management culture that applies short-term solutions, such as cheap but polluting and inefficient technologies, and fails to produce stable, long-term mining conditions for clean, efficient technology and secure business planning. We conclude that the social context of the mining economy in Suriname strongly interacts with the technologies employed. (C) 2016 Elsevier Ltd. All rights reserved.
