Monazite Mining. 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. Other heavy minerals that accumulate with monazite include gold, platinum, magnetite, ilmenite, rutile, zircon, and a variety of gemstones. The heavy sands ...

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.

Apr 29, 2008· The first consignment of Steenkampskraal monazite ore was then exported from South Africa to the United Kingdom as a source of thorium. At about the time surface mining of monazite ore waned in early 1952, a crosscut from a vertical shaft located on the Steenkampskraal koppie intersected the ore body about 30 m below the surface.

Get priceTypically, 3 to 5 percent of the metal content of monazite is thorium (in the form of thorium dioxide, ThO 2). Much of the world's current demand for thorium metal and its compounds is satisfied by mining placers along India's Malabar Coast, where wave action deposits monazite as a coarse yellow-to-brown sand on beaches.

Similarly, thorium was recovered from Egyptian monazite sand after alkaline treatment and leaching with alkaline carbonate solution (Ali et al., 2007). This process was further studied to accommodate various complex ores/concentrates. The treatment of Korean monazite concentrate using 50% NaOH (w/v) at 170 °C is also reported (Panda et al., 2014).
