How is gadolinium mined?
Gadolinium is chiefly obtained from bastnasite and monazite, where it occurs as an impurity. It also occurs in the mineral gadolinite. It is mined in the USA, China, Russia, Australia, and India.
How is gadolinium made?
Source: Gadolinium is not found free in nature but is found in a number of minerals: mainly monazite and bastnaesite. Commercially, gadolinium is isolated by ion exchange and solvent extraction. The metal can be produced by the reduction of anhydrous gadolinium fluoride with calcium metal.

silvery white
Gadolinium: Gadolinium (Gd) is a silvery white rare earth metal. That’s why silvery background is used in the picture to represent gadolinium. Gadolinium forms compounds which are used for making phosphors for color television tubes.
What is gadolinium MRI?
Gadolinium contrast media (sometimes called a MRI contrast media, agents or ‘dyes’) are chemical substances used in magnetic resonance imaging (MRI) scans. When injected into the body, gadolinium contrast medium enhances and improves the quality of the MRI images (or pictures).
