Monazite concentrate production has occurred in recent years in India, Malaysia, Thailand, Vietnam, and Brazil (Fig. 10.3), in decreasing order of production (Gambogi, 2014a). Indian beach placers are the principal present-day source for the production of monazite, mainly obtained from shorelines in the states of Kerala and Orissa ( Fig. 10.3 ).

What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

Several metamorphic complexes in Southeast Asia have been interpreted as Precambrian basement, characterized by amphibolite to granulite facies metamorphism. In this paper, we re-evaluate the timing of this thermal event based on the large-scale geochronology and compositional variation of monazites from amphibolite to granulite facies metamorphic terranes in central Vietnam.

Le Grand-Fougeray monazite placer, derived from shales of the Ordovician Traveusot Formation, is the largest and the best documented of the placers in Brittany. Estimated tonnages in alluvium of the and Gras rivers are modest (1900 t of monazite in clayey gravels with a grade of 2 to 2.6 kg of monazite per ton, and a cut-off at 1 kg/t).

Thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content. Thorium is typically found in the minerals thorite, thorianite and monazite however monazite is the only mineral from which Thorium is currently mined. These monazite deposits are found in placer deposits.
