Vedanta Aluminium raises Lanjigarh refinery capacity to 5 million tonnes a year
With the expansion, Vedanta Lanjigarh now ranks as the world’s second-largest alumina refinery
Vedanta Aluminium, India’s largest aluminium producer, has increased its Lanjigarh Refinery capacity to 5 million tonnes per annum (MTPA), a significant step towards strengthening India’s self-reliance in aluminium.
A company statement said with the expansion, Vedanta Lanjigarh now ranks as the world’s second-largest alumina refinery (ex-China). It has boosted India’s total alumina refining capacity to nearly 13 MTPA and makes the country the third-largest producer globally.
“The Lanjigarh facility alone contributes 38 per cent of India’s total alumina output, making it the largest single-location alumina refinery in the country,” it said.
The statement said the milestone underscores Vedanta Aluminium’s commitment to building a globally competitive aluminium ecosystem for the country, as domestic demand accelerates across sectors such as infrastructure, automotive electric vehicles, renewable energy, construction, railways, and aerospace.
68% y-o-y growth
On the other hand, the refinery achieved its highest-ever monthly alumina production of 254,000 tonnes in November, marking an 8 per cent month-on-month increase and a 68 per cent year-on-year (y-o-y) growth. It also handled over 700 rakes, the highest ever in a single month, achieving the lowest specific power consumption in 20 months. This led to reduction in conversion costs to an 18-month low, the company said.
It quoted Rajiv Kumar, CEO, Vedanta Aluminium, as saying, “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 reflects our commitment to responsible resource development, innovation, and long-term value creation for the nation.”
Pranab Kumar Bhattacharyya, CEO, Vedanta Alumina Business, said, “From concept to commissioning, every stage of the expansion has been driven by precision, agility, and collaboration.”
Starting as a 2 MTPA greenfield facility, the Lanjigarh refinery embarked on an ambitious expansion journey in 2020.
