The present study aims to investigate the textural, mineralogical and geochemical characteristics of lean grade placer monazite from Bramhagiri beach sand deposit assess possibility for its use in industrial applications. bulk back dune with 18 samples showed elements uranium thorium traces, phosphorus calcium minor amounts, alumina, silica titanium major amounts. Since apatite was absent this ...

The monazite-type solid solution of LaPO4 and EuPO4 has been studied by X-ray diffraction, infrared (IR) and Raman spectroscopic techniques. A substantial excessmolar volume has been derived from the X-ray data, and the Raman and IR spectra show band broadening typical for mixing of cations of different size on the cation sublattice. The IR spectra were interpreted by the autocorrelation method...

Carbonatite intrusive complexes are important hosts for Rare Earth Elements (REE) deposits and commonly affected by surficial weathering processes. Mount Weld REE deposit of Western Australia is one the world’s richest here we present whole-rock mineral geochemical data on compositions primary weathered carbonatites. The concentrations in magmatic carbonatites at vary two orders magnitude, sugg...

There are significant tin reserves in the dumps and tailings from Llallagua. Currently, this waste is being processed using gravity concentration or a combination of with final stage froth flotation. A process mineralogy study their products after processing Llallagua was carried out to determine failings system order contribute designing an improved new scheme. The feed tailings, concentrate, ...
