The relative abundance of feldspar in the non-magnetic fraction supports the efficiency of magnetic separation for reuse of oxygen carrying particles. However, the presence of Fe-rich phases such as Fe 2 TiO 5 and FeTiO 3 suggests that even parts of the non-magnetic fraction exhibit oxygen carrying abilities and are lost in the waste streams.
