A life cycle assessment of mine tailings management
MetadataShow full item record
This study of life cycle assessment and environmental valuation of mine tailings management combines rheology analysis, and computer simulations. Three strategies were assessed: thickened tailings, tailings paste, and filtered tailings. Technology improvement and renewable energy were introduced in order to improve the sustainability performance of the mine tailings methods investigated. Alternative Tailings Disposal methods with filter belt press and stack cell flotation together with renewable energy helped to reduce the environmental impact and costs associated with coal tailings disposal.

Fleming, P.; Valentine, L.; Bateman, Bill (2013)Caudal autotomy is a common defense mechanism in lizards, where the animal may lose part or all of its tail to escape entrapment. Lizards show an immense variety in the degree of investment in a tail (i.e., length) across ...
Bateman, Bill; Fleming, P.; Rolek, B. (2014)Many lizard species use caudal autotomy to escape entrapment. Conspicuous coloration may increase the likelihood of being attacked, but if that attack can be directed towards the autotomous tail this may ultimately increase ...
Young calcareous soil chronosequences as a model for ecological restoration on alkaline mine tailings.Cross, Adam; Lambers, H. (2017)Tailings are artificial soil-forming substrates that have not been created by the natural processes of soil formation and weathering. The extreme pH environment and corresponding low availability of some macro- and ...
