Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.Monazite Price - Select 2020 high quality Monazite Price products in best price from certified Chinese manufacturers, suppliers, wholesalers and factory on SBM

Management of radiation hazards from mining of mineral .

milling and chemical processing for the extraction of the rare earth elements and compounds. Depending on the monazite concentration in the raw sand, radiation exposures of the order of 0.13–1.00 man·mSv per tonne are involved in the mining and separation of monazite. The chemical extraction of rare earths from monaziteThe treatment of Korean monazite concentrate using 50% NaOH (w/v) at 170 °C is also reported (Panda et al., 2014). In an alkaline treatment of Egyptian monazite in ball mill autoclaves, grinding, and decomposing of monazite take place simultaneously (Abdel-Rehim, 2002).

Beach sand deposits on the east coast of Australia are a major source of rutile and zircon, and supply 80 per cent or more of world requirements. The deposits also contain a small amount of monazite, averaging about 0.5 per cent of the total heavy minerals.After banning mining of river sand and other minor minerals without the mandatory environment clearance [2], the National Green Tribunal (NGT) has now banned beach sand mining from the sea coasts of Tamil Nadu and Kerala.The ban was in response to a petition filed by the NGT Bar Association, which among other environmental risks enumerated risk of radiation from the mining of beach minerals .

Beach sand in India contains a range of economic minerals and is mainly mined by dredging, although dry mining also takes place (IREL, 2013b). Some of the minerals, notably monazite, contain high levels of both REE and Th. Thorium is an asset for future Th-fuelled nuclear reactors in India, thus theseA serious attempt was made about 1909 to utilize the monazite contained in the tremendous quantities of hydraulic tailings lying in the Boise Basin fields. A 1,000-ton plant was built, comprising tables, drier, screens, and several magnetic concentrators. A 95-percent monazite sand could be made, containing about 5 percent thoria.
