Description: Rare Earth Mineral Sand Concentrate - 1/2 Kilo Amount. Concentrates from my Colorado placer mining project. Concentrates were produced with Pan Am Duplex jigs and then gravity separation tables. We have used gravity separation to extract the freegold; these are the remains. 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 45% - Combined ilmenite, euxenite, columbite and rutile 27% - Monazite 14% - Garnet 3.4% - Other heavies including zircon, silica
