With the unprecedented rate of mining and mineral processing over the past decade, there
has been an increasing level of concern worldwide about the fate of tailings and the …

The oxidative dissolution of sulfidic minerals releases the extremely acidic leachate, sulfate
and potentially toxic elements eg, As, Ag, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Th, U, Zn, etc. from …

Lakes developing in former coal mine pits are often characterized by high concentrations of
sulfate and iron and low pH. The review focuses on the causes for and fate of acidity in these …

Disposal of untreated and treated mining wastes and tailings exerts a significant threat and
hazard for environmental contamination including groundwater, surface water, wetlands …

Far from equilibrium, quasi-steady state dissolution rates of an iron rich chlorite (Mg2.
76Fe2+ 1.90 Fe3+ 0.07 Al0. 97)[Si2. 48Al1. 52O10](OH) 8, have been measured as a …

A series of laboratory column tests on reactive mine tailings was numerically simulated to
study the effect of high water saturation on preventing sulfide mineral oxidation and acid …

Two sulfidic mine tailings within the Zambian Copperbelt in the north of Zambia have been
studied: Chambishi, representing an old site (age about 40y) and Mindolo, which represents …

The use of covers with capillary barrier effects (CCBEs) for reducing acid mine drainage
(AMD) from sulphidic mine tailings is simulated using the MIN3P finite volume model for …

This paper describes the processes leading to uranium distribution in the groundwater of
five boreholes near a restored uranium mine (dug in granite), and the environmental impact …

Nanoscale zerovalent iron (nZVI) has shown potential to be an effective remediation agent
for uranium-contaminated subsurface environments, however, the nature of the reaction …
