n. A reddish-brown phosphate mineral containing several rare-earth elements, PO4, important as a source of cerium and thorium. Monazite definition is - a yellow to red or brown mineral that is a phosphate of thorium and various rare earth elements and occurs especially in sand and gravel deposits. Processing of monazite sands Abstract For the past ten years, much effort has been expended by several research teams to develop an economic process for recovering thorium, rare earths and uranium from monazite sands. Recently, a process was developed at the Ames Laboratory which possessed many attractive features.

Monazite sand was quickly adopted as the thorium source and became the foundation of the rare-earth industry. In some of Brazil's HBNRAs, monazite sand deposits are abundant on certain black sand beaches. The external radiation levels on these black sand beaches reach as high as 50 μGy h −1 . The minerals that are present in abundance in these coastal regions of Brazil are monazite, rutile, ilmenite, zircon, cassiterite, thorianite, pyrochlore and niobate-tantalite.

Monazite is a thorium-bearing mineral that occurs in sand deposits in a number of places around the world. Only a small proportion of the sand in this sample is actually monazite: It is probably somewhat selected compared to normally occurring sand deposits, but not much.

A descriptive flow sheet of tne process is shown in Figure 1. The sands are ground to 95 per cent minus 65 mesh, end then digested in 93 per cent sulfuric acia for four hours at 210°C. The acid to sand weight ratio, based on 100 per cent sulfuric acid, is 1.56.
