Acid rock drainage (ARD) is one of the most important long–term environmental issues for the world-wide mining industry. The source to ARD is mainly oxidation of sulphides such as pyrite (FeS2) or pyrrhotite (FeS) that could be residuals in open pits and waste rock after mining operations. When the sulphides are exposed to atmosphere, they will oxidize in an acid generated reaction that will enhance the weathering of other sulphides containing heavy- metals such as Cu, Cd, Pb and Zn. This may result in an acidic metal rich drainage that may affect the recipients outside the mining area.
The aim of this project is to design and evaluate a technology that reduces the environmental impact from previously backfilled open pits containing sulphides. Rest products such as fly ash, incineration residues, and green liquor dregs from e.g. the paper mill industry will be tested to reduce the sulphide oxidation. The project involves geochemical investigations in laboratory and in the field at closed mine sites. The work involves travelling to remote mine sites.
The project is performed at the Division of Geosciences at Luleå University of Technology. The work will be carried out in cooperation with the mining industry, and other industrial actors in the field of environmental engineering. The duration of the scholarship is two years.
Qualifications
The applicant should have a PhD degree and experience in geology and geochemistry related to mining environmental research, and experience of laboratory and field work. The researcher is expected to be able to carry out own research projects but also to cooperate with the industrial partners.
Requirements:
Language: Good knowledge in English is required
Driving licence is required (valid in Sweden).
Basic knowledge in soil mechanics and Hydrogeology is meritorious.
