Vedanta Chairman Anil Agarwal said the group's aluminium business can double capacity to 6 million tonnes in about three to three-and-a-half years and has a longer-term vision to reach 10 million tonnes in around five years, as Vedanta completed the listing of its demerged businesses on Indian exchanges. In an exclusive interview with CNBC-TV18, Agarwal said Vedanta Aluminium is fully integrated and among the lowest-cost producers globally. "Price will go up, price will go down. I am lowest cost producer in the world. Fully integrated. I have started producing 3 million tonne, going to be 6 million tonne. And vision is to go for 10 million tonne," Agarwal told CNBC-TV18. Asked when the business could reach 6 million tonnes and 10 million tonnes, Agarwal said the first milestone could come in "three, three-and-a-half years" and the larger target in "five years". He said aluminium demand remained high, though prices would continue to move in cycles.
