Comparative life cycle assessment of tailings management

Oct 15, 2021 · Copper recovered from tailings through electrodialysis could be further electrowon as pure metallic copper, which is as pure as or purer than electro-refined copper (Schlesinger et al., 2021). For simplification purposes, this study assumed that the economic value of the recovered copper from tailings was the same as copper in concentrate.

Rehabilitation plans and other environmental aspects of

Gold mining tailings often carry high levels of arsenic and mercury. Rehabilitation should ensure that the retreated tailings are confined in properly constructed and rehabilitated tailings dams, so as to prevent contamination. Tailings removal should ensure that all contaminated material is removed or stabilised prior to revegetation.

GEA decanters improve management of tailings

Traditionally, mine tailings, in the form of a slurry containing fine mineral particles, have been contained in large, man-made lakes where the solids are allowed to settle out and then the cleaned water skimmed off the surface. However, this process is less than ideal. Settling takes a long time which means tailings ponds can become quite large.

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100% % Cu Loss = 10095.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.
