Rare Earth Analysis

Rare earth element analysis expertise.

Intertek has an extensive experience analyzing for these elements and offers a number of Total Quality Assurance analytical packages suitable for rare earth elements, high field strength elements, major elements, trace elements and naturally-occurring radioactive elements with which rare earths are commonly associated. 

Rare earth analysis support:

• Grassroots exploration
  • Mineral exploration geochemistry
   
• Resource estimation
• Advanced projects
• Metallurgical products
• Lithogeochemical applications

Rare earths analysis can be performed on different media such as soils, rocks and vegetation using aqua regia, four acid digests or fusion digests with ICP-MS finish. Light rare earths may be quantitatively recovered in aqua regia or four acids digests whereas minerals hosting heavy rare earths may require a more aggressive fusion digest for complete dissolution. Aqua regia is useful technique for grassroots exploration and identification of geochemical anomalies. Fusion digests using lithium borate or sodium peroxide are ideally suited for complete recovery of all rare earths elements.
