Mine tailings dams: Characteristics, failure ...

The ratio of tailings to concentrate is commonly very high, generally around 200:1 (Lottermoser, 2007).Moreover, as the point of peak metal production is surpassed, the extraction of lower grade ore is an established long-term trend (Mason et al., 2010).For example, in Australia the average Cu grade was c. 10% in 1885 but it fell to 1% by 2005, whereas in Canada the average Ni grade was c. 5% ...
