    The HREE individual elemental recovery values ranged from 27.9-44.5. The mass yield of the flotation was 23. The flotation recoveries reported here are significantly lower than what was achieved previously. For the Leach after flotation process, leaching was conducted on the first concentrate of flotation.

    Rare earth mineralogy in tailings from Kiirunavaara

    Abstract. Four main and three minor rare-earth-element REE-bearing minerals were identified and quantified in the Kiirunavaara apatite iron ore tailings using optical microscopy, an electron probe microanalyzer EPMA and a mineral liberation analyzer, and their chemical compositions were analyzed by the EPMA and laser ablation inductively coupled plasma-mass spectrometry.
