1. Introduction. Artisanal mining is small-scale mining conducted by a few individuals or small groups, generally using rudimentary extraction methods such as manual tools and simple portable machines (Hilson, 2002).These techniques were common in the western United States at hardrock mining operations in the mid- to late-nineteenth century, including …
Arsenic and mercury contamination and complex aquatic …
Compared to average pre-mining arsenic levels, concentrations increased by ~5 and ~7 times during the mining and post-mining periods, respectively. Arsenic concentrations reached their highest levels (~4960 mg kg −1) in the modern sediments at Lake Charles. Compared to Lake Charles, arsenic concentrations in Loon Lake sediments were much lower.

Mining: Production and Control of Arsenic
Arsenic in the mining industry Atmospheric arsenic emissions from copper smelting represent the largest contribution of arsenic from the mining and metals industry and have been the focus of pollution control technologies and increasinglystringent regulations. Arsenic can also be leached out of some metal ores by cyanide or acid rock drainage ...
Immobilization of mercury and arsenic in a mine tailing …
It is characterized by invisible gold in carbonate minerals. Generally, gold is accompanied by an accessory suite of elements such as arsenic (As), mercury (Hg), and others (Ilchik and Barton, 1997). The gold mining and refining activities leads to a widespread pollution of toxic elements (e.g., Hg and As) in the environment (Ning et al., 2011).
JV video: How Dundee cuts cyanide from gold processing and locks up arsenic
Its GlassLock process stabilizes arsenic — a growing problem in mining as companies tap more metallurgically complex deposits — so it's not released into the environment during processing.
