Research and interventions around artisanal and small-scale gold mining (ASGM) largely focus on mercury (Hg) use, reflecting the sector's status as the largest global source of anthropogenic mercury release to the environment (UNEP, 2019) and the influence of the Minamata Convention, which seeks to curb global mercury pollution.However, artisanal …
The Mercury Problem in Artisanal Gold Mining. Mercury-based artisanal and small-scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to …
Naturally, when gold-seeking humans figured this out, it became a convenient way to separate liberated gold particles from the sand and other undesirables. Mercury has been used for the past fifty years in artisanal small-scale mining methods in …
Mercury used in gold mining can be a problem that includes environmental risks and health risks for miners and others.

Enforcement against illegal gold mines in the Brazilian Amazon ramped up in 2023, but the contamination from the mercury used in mining will likely be felt for generations to come.
Despite this, the mercury amalgamation process was highly inefficient, recovering only about 30% of the gold, leaving significant grades of gold in the tailings. This led to the introduction of improved extraction methods like VAT leaching and Carbon-in-Pulp (CIP) or Carbon-in-Leach (CIL) technologies, which offered higher recovery rates.
The government has reaffirmed its commitment to eliminating mercury use in the mining sector through its partnership with PlanetGold, a five-year initiative aimed at improving mining practices ...
Artisanal and small-scale gold mining (ASGM) is present in over 80 countries, employing about 15 million miners and serving as source of livelihood for millions more. The sector is estimated to be the largest emitter of mercury globally. The Minamata Convention on Mercury seeks to reduce and, where feasible, eliminate mercury use in the ASGM. However, …
President Museveni signed the Mining and Minerals Act 2022 into law in October 2022, marking a significant step towards regulating the mining sector and safeguarding environmental and public health. Among its provisions was a ban on the use of mercury in mining activities, a move aimed at curbing its detrimental effects.

Located in Nevada County, California, Malakoff Diggins State Historic Park was the Sierra Nevada's largest hydraulic gold mine, operating from 1866 to 1884. Historically, part of the process of hydraulic mining included using mercury to extract gold from produced sediment through the process of amalgamation.
Abstract: Mercury is still used in the amalgamation process in small-scale gold processing. This study aims to evaluate the mercury contamination of various environmental media in the artisanal small-scale gold mining (ASGM) area in the Simpenan District, Sukabumi Regency.
