Non Magnetic Rare Earth Mineral Sand Concentrate - 1/2 Kilo Amount.
Concentrates from my Colorado placer mining project. Concentrates were produced with Pan-Am style duplex jigs and then secondary upgrading using gravity separation tables. Concentrates are then dried and then magnetic separation takes place to produce this concentrate.

The non-magnetic fraction of this concentrate contains approxiamtely 40% TREO.

Great for research, extraction projects, and as a collectible. Note they still contain some amounts of gold – these should run ¼ ounce a ton according to fire assay from Hazen Research. In addition, according to xrf analysis these concentrates do contain the suite of platinum group metals. If you can extract them – let me know!!

Approximate Composition

40% - Monazite
20% - Non identified metalics (non-magnetic)

30% - Garnet
10% - Other heavies including zircon, silica
