Analyses of fluorapatite grains reveal that they contain an average of 0.233 per cent thorium (Hussey, 2003), making the Nolans Bore deposit a world-class thorium resource. Concentrations of thorium may also be found in iron oxide Cu-Au, skarn and phosphate deposits, and in coal and peat accumulations.

Thorium occurs in several thorium minerals including althupite, auerlite, cleveite, ekanite, euxenite, huttonite, monazite, polucrase, steacyite, thorianite, thorite, yttrialite and zirkelite. However, thorite ( ThSiO 4 ), thorianite (ThO 2 + UO 2 ) and monazite contains high percentage of thorium than the rest of thorium mineral.

Thorium Deposits - an overview ScienceDirect Topics

For now, the production of thorium as the primary product is generally regarded as uneconomic (NEA-IAEA, 2014). In the foreseeable future, the economic production of thorium is most likely to occur through the byproduct or coproduct of production of another mineral commodity of value, such as REEs or titanium minerals in heavy-mineral sands.

US8221520B2 - Production of thorium 228 starting

The invention relates to a process for producing 228 Th from a natural thorium salt, which comprises in succession: a) the separation of the radium from the other radioelements present in this salt, by at least one coprecipitation of the radium by barium sulphate, this coprecipitation comprising: i) the addition of sulphuric acid and a barium salt to an aqueous solution of said natural thorium salt in order to form a

Locations of Deposits

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.
