30-10-2017· Currently, there are no mines that exclusively or primarily mine thorium since global demand is low, ranging from a few tens of tons a year. Thorium is mainly mined from different minerals like thorite, thorianite, and monazite which is a by-product of mining of rare earth minerals.

Thorium-232 is the most stable isotope of thorium and accounts for nearly all natural thorium, with the other five natural isotopes occurring only in traces. Thorium is estimated to be about three to four times more abundant than uranium in the Earth's crust, and is chiefly refined from monazite sands [ Monazite contains 2.5% thorium ][Monazite is a widely scattered on the Kerala Coast].

Monazite Sand an overview ScienceDirect Topics

Thorium is produced commercially from monazite sands. After mining, the monazite sands are concentrated magnetically and then treated with either hot, concentrated sulfuric acid or hot, concentrated sodium hydroxide. The acid treatment dissolves the thorium phosphate present, while the basic process converts the phosphates to insoluble hydroxides.

Thorium in Australia Parliament of Australia

Thorium is found in small quantities in the earth s upper crust where, at 6 10 parts per million, it is about three times more abundant than uranium. The main source of thorium in Australia and worldwide is the mineral monazite which is a reddish-brown rare-earth phosphate mineral. Monazite contains 8 10 per cent thorium.

Monazite an overview ScienceDirect Topics

Monazite is isostructural with huttonite (ThSiO 4), cheralite (CaTh(PO 4) 2), gasparite, and roosevelite (Table 7) and displays variable degrees of solid solution among the endmembers (Förster, 2006). Thus, natural monazite often contains thorium (Th) and arsenic (As) as major elements (Hoshino et al., 2012b; Ondrejka et al., 2007).
