Arable soils may act as a sink in the global carbon cycle, but the prediction of their potential for carbon sequestration remains challenging. Amongst other factors, soil aeration is known to influence root growth and microbial activity and thus inpu

Temperature is an important factor affecting the leaching of contaminants from waste deposits, especially in the Nordic region where temperature change is more drastic than other areas. In this study, the impact of temperature variation in the leachi

Vanadium – a transition metal – is found in the ferrous-ferric mineral, magnetite. Vanadium has many industrial applications, such as in the production of high-strength low-alloy steels, and its increasing global industrial consumption requires n

Multicomponent reactive transport modeling using PHREEQC of a Ni-sulfide tailings deposit was undertaken to assess how effective locally-obtained mineral dissolution rates in simulating long-term kinetic testing results of the tailings material. Fors

Metal release from the deposition of sulfide-containing tailings in seawater was investigated using a batch reaction experiment inside a temperature and dissolved oxygen-controlled chamber. Two hundred grams of tailings from a porphyry Cu-Au and a se

Dry covers can be applied above tailings to reduce and prevent formation of acid mine drainage and leaching of contaminants. Efficiency of covers is affected by different parameters, of which temperature change under climate change context is one. He

The dissolution rates of forsterite and pyrrhotite in a mine tailings deposit as a function of pH were obtained using kinetic testing (leaching test) and PHREEQC inverse modeling. Leach columns containing nickel sulfide mine tailings from four locati
