The heavy mineral fractions were further separated magnetically using a very strong hand magnet to collect the strongly magnetic fraction (VM), and a Frantz Isodynamic
Separator to isolate the non and slightly magnetic fractions.
Laboratory magnetic separators include the Magnetic Barrier Laboratory Model LB-1 and Isodynamic
Separator Model L-1, which separate minerals according to magnetic susceptibility.
Grains from the least magnetic split obtained with a Frantz isodynamic
separator were hand picked in alcohol under a binocular microscope.
Mineral separation involved the use of a Wilfley Table, heavy liquids (bromoform and methylene iodide) and a Frantz Isodynamic
Heavy mineral concentrates were prepared using standard crushing, grinding, Wilfley[TM] table, and heavy liquid techniques, Mineral separates were sorted by magnetic susceptibility using a Frantz[TM] isodynamic
