Oct 16 2015 Spectacular alteration of monazite by diagenetic/hydrothermal brines is well documented in some Proterozoic sedimentary basins in close relationship with high grade uranium U deposits Hence monazite has been proposed as a viable source for some U deposits However monazite alteration remains enigmatic with regard to its high stability in

Aug 19 2018 This work presents a selective process route for REE extraction from iron rich monazite ores The process involves sulfation by addition of concentrated sulfuric acid and pyrohydrolysis at temperatures of approximately 700–750 °C Experimental results show REE extraction higher than 70 and low iron below 5 and thorium extraction below
Monazite is a primarily reddish brown phosphate mineral that contains rare earth elements.Due to variability in composition monazite is considered a group of minerals The most common species of the group is monazite Ce that is
