ODM HMC paramagnetic separation

ODM Magnetic Separation. HMC concentrates are separated into 4 separate paramagnetic/magnetic fractions to facilitate indicator mineral picking.

The > 1 amp fraction is further separated by heavy liquid (S.G. 3.2)

[This suite is very similar to #309 – the only difference being the inclusion of a heavy liquid separation on the > 1 amp fraction).]

General Methodology:

Overburden Drilling Management magnetic/paramagnetic separation. Sample fractions are separated using a high intensity lift-type induced roll separator (Carpco Model MLH (13) 111-5). The strongly paramagnetic fraction was removed first (current set to 0.6 Amp), then the moderately paramagnetic fraction (0.8 Amp), and finally the weakly paramagnetic fraction (1.0 Amp), leaving behind the non-paramagnetic fraction.
