Minerals Beach Sands Concentration

Minerals Beach Sands Concentration

Because of their high density, monazite minerals concentrate in alluvial sands when released by the weathering of pegmatites. These so-called placer deposits are often beach or fossil beach sands and contain other heavy minerals of commercial interest such as zircon and ilmenite. Monazite can be isolated as a nearly pure concentrate by the use ...

Beach sands, the focus of present interest, are mostly composed of quartz, feldspar and other minerals, their coarse-to-finely divided constitution resulting from the abrasive action of wave-motion, weathering and general erosion of metamorphic or igneous rocks and soil or both (Kurt and Berker, 2014, Papadopoulos et al., 2016, Veiga et al., 2006).
