Efficiency of heavy liquid separation to concentrate magnetic particles
The yield of the magnetic extracts for the same sample set using a much higher amount of starting material (10 cm 3 of wet bulk sediment) is much lower, and cannot be meaningfully mass quantified. With the exception of the magnetic extract measurements, all thermomagnetic curves are mass normalized in the following.An …
