Abstract

This article presents research on selected materials with the aim of determining their rare earth element (REE) content and attempting
to intensify it. The test material was coal slurry, which is a waste product from the operation of a preparation plant of a closed coal
mine. Research on REE concentration intensification tests was carried out using magnetic separation. Laboratory analyses determining
the REE content in the samples obtained, were carried out using the inductively coupled plasma ionisation mass spectrometry (ICPMS)
technique. Carrying out this research by the KOMAG Institute of Mining Technology, is a continuation of work related to making
mining waste economically useful and determining a new source of REE recovery. Previous research and development work showed
REE content (scandium 40.49 ppm) in the coal slurries studied. The result of the work carried out is the determination of the economic
utility of REE recovery from the studied waste.
