بیشترMonazite. Monazite is a phosphate mineral [ (Ce,La,Nd,Th)PO4], the major commercial source of Ce. Occurring as small heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite contains up to 27wt% of U and Th oxides. From: An Introduction to Nuclear Waste Immobilisation (Second Edition), 2014.
بیشترThe successful industrial application is reported in Australia for the selective separation of ilmenite, rutile, zircon and monazite by means of electrostatic separation, together with magnetite separation in view of their different magnetic and electrical properties at various elevated temperatures (Australia, 2019; Farjana et al., 2018; Jones ...
بیشترMost of the monazite grains are reversible negative and are attracted towards the positively charged static electrode. Using wet gravity concentration, both low and high intensity magnetic separation, and electrostatic separation techniques, a high grade concentrate assaying 97 wt. % monazite with a recovery of 76.8% can be obtained.

بیشترThe lanthanides hydrous oxides produced from the Egyptian Monazite contain about 45% cerium of the total lanthanides. The high concentration of Ce in this matrix complicates separation of different lanthanides from each other. In this paper a method was developed to separate cerium quantitatively from the lanthanide cake produced from Egyptian Monazite by precipitating tetravalent cerium from ...
بیشترBesides these minerals, ilmenite and zircon were the target minerals to be concentrated. Using a magnetic separation method at various magnetic intensities, paramagnetic minerals, ilmenite (0.8 T magnetic product), and monazite/xenotime (1.0–1.4 T …
