Research results published on Kiviniemi Sc upgradingResearchers of University of Oulu, Finland, have published interesting reasults concerning upgrading of the Sc content of Kiviniemi ferrous Sc concentrate produced by magnetic separation by high temperature reduction of iron oxide and separation of metallic iron.
Sc will not be incorporated into metallic iron, but is concentrated in the slag phase.
Iron free slag composition will help selectivity of Sc leaching and precipitation of pure Sc oxide procuct.
Iron metal might a saleable product, although containing high amounts of phosphorous.
