Model Answer
Global Distribution of Rare Earth Elements (REE)
Rare earth elements (REEs) are widely distributed in the Earth’s crust but are not typically found in concentrated deposits. China holds the largest share, with 38% of global reserves and producing about 70% of the world’s supply, particularly from regions like Baotou and Jiangxi (Source: Geology Reports). Vietnam (19%) and Brazil (18%) have significant reserves, but their production is lower. Other notable producers include Russia (10%), India (6%), and smaller reserves in Australia (3.5%) and the USA (1.3%) (Source: Mineral Resources of the World).
Distribution of REE in India
In India, monazite is the primary source of REEs. Major deposits are found in beach sands of Kerala, Tamil Nadu, Andhra Pradesh, and Odisha. Other notable reserves are in Meghalaya and Rajasthan (Source: Indian Geological Survey).
Economic Importance of REE
REEs are vital in high-tech industries, especially for manufacturing permanent magnets used in electronics, electric vehicles, and renewable energy systems. They are also critical for green technology, improving energy efficiency, and miniaturization of devices (Source: Technology and Economy Journals). Additionally, cerium is used in glass polishing, and scandium is crucial in aluminum alloys for sporting goods. India’s growing demand for REEs underscores the need for increased domestic production to reduce dependence on imports (Source: Industrial Reports).
