Bhubaneswar: Vedanta Aluminium’s Lanjigarh refinery become India’s largest and world’s second largest in the world with its capacity scaled up to 5 million tonnes per annum (mtpa ) from 2 mtpa.

With this expansion, Vedanta Lanjigarh now ranks as the world’s second-largest alumina refinery (ex-China), boosting India’s total alumina refining capacity to nearly 13 mtpa and positioning the country as the third-largest producer globally. The Lanjigarh facility alone contributes 38% of India’s total alumina output, making it the largest single-location alumina refinery in the country.

This milestone underscores Vedanta Aluminium’s commitment to building a globally competitive aluminium ecosystem for India, as domestic demand accelerates across sectors such as infrastructure, automotive & EVs, renewable energy, construction, railways, and aerospace.

In parallel, the refinery achieved its highest-ever monthly alumina production of 254 KT in November, marking an 8% month-on-month increase and an impressive 68% year-on-year growth. This record output reflects sustained operational excellence and disciplined execution, including handling over 700 rakes, the highest ever in a single month, achieving the lowest specific power consumption in 20 months, and reducing conversion costs to an 18-month low through optimized processes and resource efficiency.

Rajiv Kumar, CEO, Vedanta Aluminium, said,“Scaling our Lanjigarh operations to 5 MTPA is both a capacity milestone and a step toward a resilient, world-class aluminium value chain. Our ramp-up, evidenced by record monthly outputs, reflects our commitment to responsible resource development, innovation, and long-term value creation for the nation.”

Pranab Kumar Bhattacharyya, CEO, Vedanta Alumina Business, added,“This achievement is a testament to the dedication and engineering excellence of our teams. From concept to commissioning, every stage of the expansion has been driven by precision, agility, and collaboration. We continue to sharpen processes, enhance efficiency, and uphold our Zero Harm culture to deliver reliable performance at scale.”

Starting as a 2 MTPA greenfield facility, the Lanjigarh refinery embarked on an ambitious expansion journey in 2020.
