Concentration Rare Ore
Analysis of the concentration in rare metal ores …
This paper focuses on developing a model to predict the mineral concentration of rare metals as a function of the particle size distribution after a cycle of the compression crushing process. In this study, compressive breakage and geochemical analysis experiments were conducted on four different rare metal ores of tantalum and tungsten.
Rare Earth Metals Extraction: ANZAPLAN
After concentration REE bearing minerals, rare earth elements have to be extracted from the concentrate. Several procedures for decomposition of REE bearing minerals are available. The major part includes thermal treatment of the ore in the presence of acidic or caustic reagents.
Local concentration of middle and heavy rare …
Rare earth elements fractionation is exhibited in the different terrain of weathered ore body. Based on this study, the finding that HREEs concentrate in the lower terrain of weathered crust elution-deposited rare earth ores, such as in the col, would become a marker or indicator to search for middle and heavy rare earth enriched zone.

Ore bodies are rare. If the concentration is poor, then you will have to process too large an amount of rock to be attractive. If the quantity in a specific location is not large, then it is simply not worth expending the capital setting up an industrial operation.
