In summer of 2021, dust and processed ore were collected from 54 villages by U.S. CDC and Nigerian colleagues after the discovery of widespread lead poisoning in northwest Nigeria, and provided to the Environmental Research Laboratory at GSU. Various geochemical analyses were conducted to assess the magnitude of Pb exposure. ICPAES determined Pb concentrations as high as 61,000 ppm.
Gold mining activity in the Sierra Nevada foothills, both recently and during the California Gold Rush, has exposed arsenicrich pyritic rocks to weathering and erosion. This study describes arsenic concentration and speciation in three hydrogeologic settings in the southern Mother Lode Gold
Aug 20, 2021 Mining must be done as efficiently and safely as possible to reduce potential impacts on the environment on human health. After all, human and environmental health is as precious as gold. This week the Ministry of Natural Resources celebrates Mining Week under the theme Extracting Minerals Underscoring safety, Protecting the Environment.
AGAT Laboratories has extensive expertise in silver, gold and PGE determinations. Precious metals such as gold, silver and platinum are in high demand in todays market. Whether the demand is for oregrade analysis or high volume baseline fire assay gold exploration work.
May 01, 2021 Modern mining often uses chemicals like cyanide to separate gold from other minerals. These chemicals can filter into human water sources and the broader environment. They are harmful to humans as well as plants, animals, and ecosystems. The Klondike Gold Rush is often cited as an important step in opening the last frontier.
Geochemistry We are the leading fullservice provider of analytical geochemistry services to the global mining industry. Sample preparation and analytical procedures tailored to meet the needs of exploration geologists, miners, mineral processing engineers, and metallurgists.
However, gold is produced in much smaller quantities, so the total environmental footprint for global gold production is smaller than some other commonly used metals, including steel, copper and aluminium. The stages that contributed the most to golds environmental impact were mining and comminution crushing and grinding of the ore.

Gold mining often takes place in remote areas where there is little existing infrastructure, so companies invest heavily in building power supplies, piped water and roads, which can create important benefits for local communities. Infrastructure, from roads to power stations, is part of the legacy that responsible miners leave beyond the life
