Karlapat Bauxite Block
Why in News?
The Karlapat Bauxite Block is in the news because India's top industrial conglomerates—including Adani Enterprises, Reliance Industries, Hindalco, Vedanta Aluminium, Powercem, and Coal India—are aggressively competing in a high-stakes government auction to acquire it.
About Karlapat Bauxite Block
- Location: Situated in the Kalahandi district of Odisha, sitting within the mineral-dense Eastern Ghats Mobile Belt.
- Greenfield Status: It remains a completely untouched ("virgin") greenfield block that has never been commercially mined.
- Estimated Reserves: Holds an estimated 207 to 220 million tonnes of high-grade bauxite, making it one of the largest unallotted deposits in the country.
- Dimensions: Spans a massive plateau area of about 9.6 square kilometers (over 3,100 hectares) with a thick ore bed averaging 12 to 15 metres.
- High Quality Ore: Records an exceptionally high alumina content of roughly 45.2% to 47% (primarily gibbsitic mineralogy) coupled with low silica content, allowing for highly efficient extraction via the low-temperature Bayer process.
- Past Legal Hurdles: The Odisha High Court previously halted an auction of this exact block in 2021 due to deep-seated concerns regarding forest degradation, local water streams, and wildlife habitats.
