FAQ

Those who are looking for an answer to the question «Which is the best way to decompose xenotime concentrate?» often ask the following questions:

👉 Which is more difficult to decompose monazite or xenotime?

  • (4) Generally, xenotime is more difficult to decompose than monazite. Several methods have been used, i.e., concentrated sulfuric acid, alkaline solution at elevated pressure, fusing with molten caustic soda, and mixing with sodium carbonate and roasting.

👉 Which is the best way to make xenotime?

  • Several methods have been used, i.e., concentrated sulfuric acid, alkaline solution at elevated pressure, fusing with molten caustic soda, and mixing with sodium carbonate and roasting. The flow-sheets of these three typical processes are shown in Fig. 40 ( Gupta and Krishnamurthy, 1992 ). Table 12.

👉 Which products are made of xenotime?

Xenotime is typically a by-product of monazite processing and as such, its processing follows a similar path to that of monazite (Cheng et al., 1994; From: Minerals Engineering , 2013 Related terms:

How is xenotime made?

Xenotime, a phosphate ore, is one of the valuable mineral deposits of rare earths similar to monazite. The main characteristics of xenotime are listed below: (1) The content of yttrium is high while that of the light rare earths is low (Table 12). (2) The content of thorium is lower than that in monazite (Table 13). (3) The composition of tungsten-containing xenotime is very complicated.
