| Characterization of Mobility and Leaching from Redox Sensitive Materials |

Redox sensitive elements are an environmental challenge, and materials such as Blast Furnace Slag and mining waste may in certain conditions generate acid leachates. There is a need to improve the characterization of such materials to be able to manage them in an environmentally safe way. This project will seek to improve the characterization of redox sensitive materials, and test the feasibility of a suggested treatment method for mining waste based on green liquor dregs (GLD). One master thesis will study pulping wastes and abandoned mine remediation. The application of green liquor dregs and other pulping by-products to the solidification/stabilisation of copper mine tailings wil be evaluated and in particular the potential of using GLD for the treatment of old tailings. Another master thesis is planned to focus on methods to characterize redox sensitive element bearing materials with the objective to develop a procedure to characterize them. 
Results from batch compliance leaching test at L/S 10 with As-polluted soil (Maurice et al 2007).
The oxidation front is often visible in tailings i.e. the oxidised tailing is red while the reduced sulphides are black or grey.
