Heavy mineral separations on some of the ordinary sands indicate that very little of the thorium, uranium, and potassium in a common sand is associated with the heavy detrital grains. Neglecting a very minor feldspar content, the radio activity of the common sandstones studied is contained almost entirely in the quartz, where it appears to be largely related to microscopic and submicroscopic

All the evaluated thorium resources in India is confined to the mineral monazite occurring in the beach sand heavy mineral suite of East and West coasts. Indian resources fall under the category VI. Placer and residual deposits of hill and valley wash of UNFC system and the deposits have been classified in
can be optimized for thorium fuels. Thorium was used in a BWR at the Elk River reactor in Minnesota, USA, from 1963 to 1968. Thorium fuel was also tested in the 60 MW(e) BWR in Lingen, Germany, until 1973. Heavy water reactors could offer excellent neutron economy and

THORIUM [Data in kilograms gross weight unless otherwise noted] Domestic Production and Use The worlds primary source of thorium is the rareearth and thorium phosphate mineral monazite. In , monazite may have been produced as a separated concentrate or included as an accessory mineral in heavymineral concentrates.

containing heavy minerals. The ultimate source of thorium minerals will be granitic rocks and veins exposed during uplift and erosion. However, during the evolution of coastlines several episodes of remobilization, deposition and enrichment can occur, resulting in mineral contents greater than the original source granites.

3/20/2013;32;This worldclass mineral sand has an inferred resource of some 900 million tons at a grade of ~10% total heavy minerals (THMs) from which highgrade concentrates of zircon, rutile and leucoxene are extracted and titanium slag and pig iron are produced. Gangue minerals consist of garnet, pyroxene, kyanite, amphibole, apatite and monazite.
Gangue minerals consist of garnet, pyroxene, kyanite, amphibole, apatite and monazite. Several other resources including satellite deposits proximal and distal to the mine area, extensive diamond mine dumps and presentday beach placers demonstrate the vast heavy mineral

4/28/20140183;32;The beach sands of Tamil Nadu and Kerala are rich in several heavy minerals such as ilmenite, rutile, leucoxene, garnet, sillimanite, zircon and monazite. These minerals are used in several industries from steel and electronics to jewellery and ceramics. Monazite, however, contains thorium, a nuclear fuel of much interest.
Other heavy minerals produced as coproducts from some deposits are sillimanite/kyanite, staurolite, garnet, and, for the recovery of REEs and thorium, monazite. Monazite, one the heaviest minerals in the heavymineral suite, is the dominant REE and Thmineral in heavymineral sands (Fig. 10.2).
Mining and Crude Separation Heavy Mineral Placer Sands / Float Separation. The most common way that Thorium used to be separated in the west was from placer sands mined for other material such as Titanium Oxide, the companion mineral containing Thorium was mostly Monazite. A placer sand mine is literally the sand placed over time via erosion

Thorium resources in heavy mineral sand deposits Most of the known thorium resources in Australia are in the rare earththorium phosphate mineral monazite within heavy mineral sand deposits, which are mined for their ilmenite, rutile, leucoxene and zircon content.
Most thorium resources are found in heavy mineral sands such as those in the Murray Basin, which are derived from the erosion of er rocks, where thorium is contained primarily in monazite grains. Thorium is also concentrated in igneous processes.
