Description: 40% Rare Earth Mineral Sand Concentrate - 1 Kilo Amount. These concentrates have all the magnetite fraction removed. The concentrates were run through a laboratory SX plant. The results confirmed a 40% TREO. Concentrates are 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. 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
