Small-scale gold mining (SSGM) is a vital sector of the global mining industry, employing over 15 million people and contributing approximately 20% of the world’s gold supply. While it provides essential livelihoods for millions, this sector grapples with significant challenges, including environmental degradation, public health risks, and links to criminal activity.
The Environmental Footprint of Small-Scale Gold Mining
The environmental impact of artisanal and small-scale gold mining (ASGM) is extensive and multifaceted. Key issues include:
Mercury Contamination: Mercury is widely used in gold extraction due to its effectiveness in capturing gold particles. However, it poses severe risks to both human health and ecosystems. Once released, mercury enters waterways, contaminating fish populations and bioaccumulating in the food chain, leading to neurological damage, particularly in children.
Deforestation: The clearing of forests for mining operations destroys critical ecosystems, especially in biodiversity-rich tropical regions. This loss of habitat has cascading effects on local wildlife and contributes to climate change.
River Sedimentation and Soil Erosion: Mining activities lead to sedimentation in rivers, affecting aquatic habitats and drinking water sources. Soil erosion further degrades landscapes, exacerbating environmental damage.
These impacts extend beyond local ecosystems, affecting communities and biodiversity across vast regions. The sector indirectly supports around 100 million people, making it the largest extractive industry by employment worldwide.
Mercury Pollution: A Global Health Crisis
Health and Environmental Consequences
Mercury pollution from small-scale gold mining is a pressing global health crisis. The toxic substance:
Contaminates local waterways, affecting fish populations.
Bioaccumulates in the food chain, impacting wildlife and human health.
Causes severe neurological damage, particularly in developing children.
Persists in the environment for decades, creating long-term health issues.
Studies in Amazon mining regions have documented catastrophic health consequences, including neurological disorders and kidney damage. The persistence of mercury in the environment creates intergenerational health problems.
Mercury Reduction Potential
Centralized gold processing facilities present a promising solution for reducing mercury use:
Reduction: These facilities can decrease mercury use by up to 95%.
Gold Recovery: They can increase gold recovery rates by approximately 40%.
Toxic Exposure: They significantly lower toxic exposure for workers and surrounding communities.
By providing alternatives to mercury amalgamation, these facilities improve both environmental and working conditions.
The Criminal Network Connection
Criminal Infiltration of Mining Operations
The informal nature of small-scale gold mining has made it increasingly attractive to organized crime. Without proper regulation, criminal organizations are:
Diversifying from drug trafficking into gold mining.
Extorting workers in remote mining regions.
Laundering illicit profits through gold sales.
Using intimidation to control mining territories.
In Brazil, nearly half of all gold production is linked to illegal activities, with criminal networks leveraging mining profits to expand their operations in drug trafficking and environmental crimes.
Environmental Crime Connection
The criminalization of gold supply chains directly impacts conservation efforts:
Mining operations controlled by criminal groups destroy forests without accountability.
Criminal networks obstruct environmental reforms through violence and corruption.
Pollution from illegal mining operations affects protected areas and encroaches on Indigenous territories.
As Robert Muggah from the Igarapé Institute notes, “Drug trafficking cartels and criminal gangs are diversifying into a range of commodities, including gold.”
