Argonaut Mine Tailings Pile Removal Assessment

thin layer of organic material is present over the tailings. In these areas, the soils are generally stable. However, large portions of AOC 2 and portions of AOC 3 near the lower tailings dam contain exposed gray tailings that are devoid of vegetation. These soils are easily eroded during large magnitude rain events and large gullies have formed.

Tailings Dams Where Mining Waste is Stored Forever

Stava, Italy In 1985, tailings dams built to store waste from flourite mining failed due to poor design and extreme water pressure. Two hundred thousand cubic meters (186,462 cubic miles) of tailings flowed more than 4 km (almost 2 miles) downstream at a speed of up to 90 km (almost 56 miles) per hour.

Heavy metal concentration in soil in the tailing dam

Soil contamination with heavy metals is a serious concern to food production and human health. The present study was conducted to evaluate the impact of tailings from an old mining site on heavy metal contamination of soil. Using a GPS to map out different sites around the tailing dam, soil samples were taken from under grassland at the different sites, at depths of
