Abstract:Background:
Brown coals are recognized as promising sources of rare earth elements
(REEs). Rare earths are present in both the mineral and organic parts of brown coal.
Objectives:
This study was conducted to investigate the influence of preliminary mechanical activation in the process of sample preparation prior to analyzing the concentrations of rare earth elements
in brown coal samples of various origins and compositions.
Methods:
Four coal samples from different deposits in Russia were selected for the … Show more
