Rare earth elements (REEs) are strategic metals with critical applications in modern technology, and with no satisfactory substitutes. REE minerals do not occur concentrated in geological environments unlike those of base metals or iron ores and their geological exploration is often a daunting task. Mining, beneficiation and metallurgy of REEs constitute a complex process with adverse environmental impacts. The world REE market today is controlled by the Peoples Republic of China, which is moving ahead to impose a total export embargo on these metals by the year 2012. As a consequence, the entire world is vigorously exploring for REE minerals in an effort to counter China’s threat. There are many favourable geological milieus in our country for REE mineralization which should be targeted for exploration.
