Die hohen Nb-Gehalte in Olivin 0-136 und 0-53 lassen sich zwanglos auf nicht sauber abgetrennte Titanomagnetit-Verwachsungen in der Grenordnung von 0,2-0,4 Gew zurkfren. Olivin 0-345a mit Nb-Werten an der Nachweis- barkeitsgrenze dfte dabei wohl eher einem mittleren Gehalt dieser Minerale in unseren Gesteinen entsprechen.

1. Introduction. Titanomagnetite is a silicon-containing mineral, highly resistant to chemical attack owing to a peculiar crystal lattice of the inverse spinel type (Genshaft, 2008).Processing with known hydrometallurgical methods involves much time, concentrated mineral acids (sulphuric and hydrochloric) and high temperatures approaching the boiling …
