Rare earth mineralogy in tailings from Kiirunavaara iron

Four main and three minor rareearthelement (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 plasmamass spectrometry.

Sampling and sample preparation Samples of apatite ore and mill tailings were collected in 2010. Ore samples (later referred to as ''O'' with sample numbers) were collected within the former mining area (WGS84 coordinates 67䓰.691´N and 29䓐.674´E) from nine piles consisting of apatite ore that had been mixed by Rautaruukki Oy.

TECHNOLOGICAL CHARACTERIZATION OF PHOSPHATIC

Apatite is a mineral which occurs in abundance in phosphate rocks, but since the sample is a tailing, the concentration expected of apatite should be low. However, 1% of apatite in a tailing is still a important concentration, which can denote imperfections at
