Vedanta Aluminium has scaled its Lanjigarh Refinery operations to 5 million tonnes per annum (MTPA), making it the world's second-largest alumina refinery outside China and increasing India's total alumina refining capacity to nearly 13 MTPA.
The expansion positions India as the third-largest alumina producer globally. The Lanjigarh facility contributes 38 percent of India's total alumina output, making it the largest single-location alumina refinery in the country. The refinery started as a 2 MTPA greenfield facility and began its expansion journey in 2020.
Rajiv Kumar, CEO, Vedanta Aluminium, said, "Aluminium is a strategic metal, central to India's industrial growth and the vision of Aatmanirbhar Bharat. 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."
The refinery achieved its highest monthly alumina production of 254 kilotonnes in November, marking an 8 percent month-on-month increase and 68 percent year-on-year growth. The record output was achieved through operational improvements including handling over 700 rakes in a single month, achieving the lowest specific power consumption in 20 months, and reducing conversion costs to an 18-month low.
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."
Vedanta Aluminium is India's largest aluminium producer, manufacturing more than half of the country's aluminium at 2.42 million tonnes in FY25. The company supplies aluminium to sectors including infrastructure, automotive and electric vehicles, renewable energy, construction, railways, and aerospace.
