1. Biotic and abiotic isotope fractionation of copper and iron : From the lab to the field scale
Sammanfattning : The distribution of the stable isotopes of Cu and Fe in nature is susceptible to isotope fractionation processes during the biogeochemical cycle. Since Cu and Fe are redox sensitive metals, differences in their oxidation states can lead to variations in the stable isotope composition of the aquatic species or compounds that they form. LÄS MER
2. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes
Sammanfattning : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. LÄS MER
