  • The thirty rare earth elements are composed of the lanthanide and actinide series. One element of the lanthanide series and most of the elements in the actinide series are called trans-uranium, which means synthetic or man-made. All of the rare earth metals are found in group 3 of the periodic table, and the 6th and 7th periods. The Rare Earth Elements are made up of two series of elements, the Lanthanide and Actinide Series.
  • As one of the preferred methods for simultaneous multi-element determination, inductively coupled plasma atomic emission
    spectrometry (ICP-AES) has been widely applied to the determination of trace elements in various materials.1–5 Yet, its use in analyses of complex samples for elements at trace or ultra-trace levels is still limited, owing to insufficient sensitivity and matrix effects.6–8 Therefore, methods of ICP-AES associated with the separation and preconcentration procedures are needed.9 The solvent-extraction technique is an effective approach for the preconcentration of detecting elements and the separation of matrix elements; also, the presence of organic solvent may improve the nebulization and transported efficiencies.
  • RARE earth minerals always contain both rare earths and non–rare earths including more or less radioactive elements, and thus, the green metallurgy of rare earths is difficult as compared with other metals.[1] Bastnaesite is mainly a fluorocarbonate of light rare earths and contains only 0.1 to 0.3 wt pct of thorium; thus, it is an important rare earth source based on radioactivity safety considerations.[1]
  • At present, bastnaesite concentrate is commonly treated by calcination-acid dissolution or directly by acid dissolution or alkaline roasting for rare earth extraction,[1] but these processes require complicated operations and result in a large amount of low-concentration thorium-containing slag and wastewater, which cannot meet the requirement of thorium effluent standard.
  •  A new solvent extraction configuration allows this. After separating Sm and higher rare earths, aqueous feed containing light rare earths undergoes solvent extraction with cation exchange or solvating extractants. Pr, Nd and a fraction of the Ce appropriate for the final application is extracted. La and residual Ce are recovered from the raffinate. The loaded organic undergoes selective stripping, yielding an aqueous stream containing Ce, Pr, and some of the Nd. The Nd remaining in the partially stripped organic can be recovered as a high purity product. The proportions of Nd reporting to the mixed feed and the pure stream can be adjusted by operating parameters, allowing flexible response to product specifications and market economics.
  • Rare earths were mined by one company in 2002. Bastnäsite, a rare-earth fluocarbonate mineral, was mined as a primary product at Mountain Pass, CA. The United States was a leading producer and processor of rare earths and continued to be a major exporter and consumer of rare-earth products. Domestic ore production was valued at an estimated $28 million. The estimated value of refined rare earths consumed in the United States was more than $1 billion. The approximate distribution in 2001 by end use was as follows: glass polishing and ceramics, 34%; petroleum refining catalysts, 16%; automotive catalytic converters, 15%;
    metallurgical additives and alloys, 14%; rare-earth phosphors for lighting, televisions, computer monitors, radar, and
    X-ray intensifying film, 9%; permanent magnets, 8%; and other, 4%.
  • Altec Lansing Technologies, Inc., a leader in the market for personal computer speakers, has introduced two computer speaker systems that use neodymium and blend the art of sound with the beauty of design.
  • The paper will outline the economic importance of industrial minerals and how they are relevant to the European economy. Reference will be made to the mine to market supply chain, and the wide range of end use markets and their relative value to the Europe’s economy as a whole. It will be emphasised that without successful industrial minerals development, these markets would not perform economically and competitively. Recent trends and developments in the world trade of industrial minerals and the EU enlargement will be highlighted.
  • First medical applications were described for rare earths. These days, the uses of rare earth elements have exceeded technical and agricultural areas and are becoming part of medicine. Comprising many biochemical and pharmacological properties of clinical relevance, lanthanides have been of great interest for medical purposes. They have been shown to act as antimicrobial, anticoagulant, cytotoxic and phosphate-binding substances, while most of their effects are ascribed to their influence on Ca2+ - depending processes, which may also be involved in certain diseases.
