Penentuan Nilai Suseptibilitas Magnetik Dan Komposisi Serta Ukuran Partikel O…

ABSTRACT The value of magnetic susceptibility and variation of composition and size of iron oxide particles from natural sand collected from Rokan River Riau Province have been investigated by ball milling. Before going through the ball milling process, the magnetic and non-magnetic particles of the sample were separated using an Iron Sand Separator and a Neodynium Iron Boron (NdFeb) magnet. A…
