Abstract:
Magnetic properties and compositional identification of Padang beach sand of West
Sumatra has been conducted. The sample was milled using a 2-stage ball milling
method. In stage 1, the sample was milled for 60 hours with a milling ball size of 1.5
cm. then, for stage 2 the product of stage 1 was milled again for 30 hours with 2
variation of milling balls diameter namely 0,7 cm and 1,5 cm. The separation of
magnetic and non-magnetic particles of ball milling was product done using NdeFB
magnets. Magnetic susceptibility and mass susceptibility were determined based on
the solenoid magnetic induction value measured using the Pasco Pasco PS-2162
sensor. Meanwhile, the composition of the samples used was measured using X-Ray
Fluorescence Spectroscopy (XRF). From this study, it was found that the Fe content
of the sample milled with ball size of 1.5 cm was higher than that for 0.7 cm. The
susceptibility magnetic and mass susceptibility value increased with increasing
milling time and milling ball size.
