Monazite is a mineral belonging to the group of phosphates that contains rare earth elements, among which cerium, thorium and lanthanum stand out.Technically, monazite represents a group of four different phosphates, but since there are no major differences between them, they are still called "monazite.". The mineral was named in the year 1829 by Johann …
