Potential Risk Analysis of Tailings Dam Under Preloading Condition and Its Countermeasures [PDF]

, 2015
It is very important for mine production safety to ensure the stability of the tailings dam. Taking a flatland tailings pond as the background, a threedimensional computational model was built based on a tailings dam under mullock heap preloading ...

Efficiency of application the solidification/stabilization technique on mine tailings from the Bor

Zaštita Materijala, 2017
Disposal of mine tailings which appears during the mining activity from Bor mine, represents enormously large environmental problem, because mine tailings is highly polluted by heavy metal, in this case by copper. Therefore it is necessary to expose mine

Electrodialytic Remediation of Copper Mine Tailings

Procedia Engineering, 2005
Mining activities in Chile have generated large amounts of solid waste, which have been deposited in mine tailing impoundments. These impoundments cause concern to the communities due to dam failures or natural leaching to groundwater and rivers. This work shows the laboratory results of nine electrodialytic remediation experiments on copper mine ...
