What type of rock 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.
How is Monazite converted to sand?
However because it is dense and resists weathering, when the granites are broken down into sand by weathering the monazite is freed and concentrated into commercial quantities in alluvial stream channels and sand deposits. Most commercial deposits are found in layered beach sands.
Why is Monazite infusible?

Can monazite be mined in Australia?
However, Australia has not produced significant quantities of monazite since public objection shut down mining at Frasier Island, Queensland. All monazite mining is focused on placer deposits because they are easier to mine and the monazite is often present in higher concentrations than in hard rock deposits.
