Childhood Lead Poisoning Associated with Gold Ore

Jul 05, 2012Exposure to lead ore dust through ingestion or inhalation can result in high BLLs in children. A limited number of studies have documented environmental lead contamination or adults with elevated BLLs in small-scale gold ore–processing communities (Appleton et al. 2001; Betancourt et al. 2005; Odumo et al. 2010; Ogala et al. 2002). However

Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.

To date, most international aid targeted to artisanal small-scale mining has focused on mercury exposures from the amalgam process used to separate gold from the ore . This safer mining pilot project tested the efficacy of improved practices to meet our primary objective of reducing lead exposures to miners in this community.

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Mercury Usage in Gold Mining and Why It Is a Problem

Jul 22, 2019The problem with this method is the release of the mercury vapor into the environment. Even if the equipment is used to catch the vapor, some still can get into the atmosphere. Under the socio-economic and political conditions found in the small-scale gold mining operation, the use of mercury is often considered as the easiest and most cost

Historically, mercury has been widely used in placer gold mining to form mercury-gold amalgam with smaller gold particles, thereby increasing the rate of gold recovery. In the 1960s, large-scale mercury use stopped. In artisanal and small-scale gold mining (ASGM), however, mercury is still used, often clandestine, gold prospecting.

A major source of air pollution from mercury, artisanal and small-scale gold mining releases approximately 400 metric tons of airborne elemental mercury each year. Located in over 55 countries, small scale gold buying and refining facilities (commonly referred to as "Gold Shops") are an important part of this production process, and are a
