Abstract
Rare earth mineral (REM) recovery from tin tailings is a significant chance
for sustainable environmental practices and resource optimisation. In order to
maximise the recovery of REM from tin tailings, this study investigates the recovery
of rare earth minerals (REM) from tin tailings using gravity separation, specifically
focusing on an amang sample from Kampar Perak, Malaysia. The research utilizes a
Mozley table to separate monazite and optimizes the table's parameters using design
of experiment (DOE) software. The amang sample is characterized using X-ray
Diffraction (XRD), X-ray Fluorescence (XRF), Particle Size Analysis (PSA), and
optical microscopy. The optimization of the Mozley table parameters results in
values for water irrigation, deck angle, and time taken of 3.54, 1.08, and 1.70
respectively, yielding percentages of ThO2 (0.49%), CeO2 (2.65%), and La2O3
(0.67%). These results, however, require future validation. The study contributes to
the understanding of REM recovery from tin tailings and lays the groundwork for
further research and industrial application.
