Academic interests
My main academic interest is separation science and in particular topics related to hydrometallurgy. My experience is mainly related to leaching, solvent extraction and ion-exchange. The metals I have studied are rare earth elements, in particular Sc, Gd, and Lu; Fe, Al, etc. The rocks and minerals I have leached are among others anorthosite, monasite, rødberg, eudialyte. Use of tracers, radioactive and non-radioactive, is a highly appreciated technology.
I also work on separation of stable isotopes, in particular the silicon isotopes. Then gaseous silicon is used - a gas called silane. This is a project of high relevance for the electronic industry.
Background
Nuclear chemist from University of Oslo in 1976. Six years as research assistant including one year at CMU, Pittsburgh, PA, USA. Then eight years in hyrometallurgical industry at MEGON AS and then 15 years as senior scientist at Institute of Energy Technology including eight years as section leader at Climate Technology. since 2007 I have been running my own consultancy, Primus.inter.pares AS (www.pipas.no).
Partners
In addition to UiO, Nuclear Chemistry, I have strong collaborations with Isosilicon AS, Yara International AS, Chalmers University of Technology, and others.
