Which of them is a mineral of lanthanum?
Which of them is a mineral of lanthanum?
- A. Monazite
- B. Xenotime
- C. Euxenite
- D. All of the above
Step-by-step solution
Monazite is a phosphate mineral that contains rare earth elements including lanthanum. Xenotime primarily contains yttrium and heavy rare earths, not lanthanum. Euxenite is a complex oxide of yttrium and heavy rare earths, not lanthanum. Therefore, only monazite is a mineral of lanthanum.
