Indian aluminium producer Vedanta said last week it expects to ramp up production at its Lanjigarh alumina refinery by 300 thousand metric tons per annum in the coming fiscal year.
The firm said it plans to ramp up the site’s existing capacity of 1.5 million metric tons per annum to a total of 1.8 million metric tons per annum by significantly increasing the Odisha plant’s operational efficiency.
Lanjigarh’s increase in efficiency has yielded tangible results, including a 26-percent reduction in caustic soda consumption and a 19-percent decrease in conversion costs over the course of the current fiscal year, which ends at the end of March.
“The Lanjigarh alumina refinery is set for a record performance in 2019-20 with total production expected to increase to 1.8MT from 1.5MT in the previous fiscal,” explained the firm in a related press release.
In addition to improvements within the plant, Lanjigarh’s production efficiency improved thanks to external sources, including improved bauxite sourcing, which yielded a 9-percent drop in bauxite costs last year.
Though Lanjigarh continues to rank among the globe’s top energy consuming alumina refineries, Vedanta notes that improved efficiency at the plant also yielded a benefit for overall sustainability.
“There has been a reduced carbon intensity to 30 percent below global average of 1,500 dollar per tonne. Lanjigarh is on track to deliver aluminium cost of production exit rate in Q4 2020,” explained the company.
Vedanta Ltd. is a subsidiary of Anil Agarwahl’s London-based firm Vedanta Resources plc. The firm owns plants in India, Australia, Namibia, and South Africa.
