Page last modified on : Jan 18, 2016

The Alumina Refinery is located at Damanjodi, Odisha, approximately 14 KM from the bauxite mine at Panchpatmali. The mined-out bauxite is transported from captive mine to refinery by a 14.6 KM long single-light multi-curve 1800 tonnes per hour (TPH) capacity cable belt conveyor. The alumina produced is transported to aluminium smelter at Angul (Odisha) and to Vizag (Andhra Pradesh) port by rail.


The present capacity of Alumina Refinery is 22.75 lakh TPA. Alumina produced is used to meet Company's requirements for production of primary aluminium at smelter. The surplus alumina is sold to third parties in the export markets.

The salient features:

  • Atmospheric pressure digestion process
  • Pre-desilication and inter-stage cooling for higher productivity
  • Energy efficient fluidised bed calciners
  • Co-generation of 4x18.5 MW power by use of back pressure turbine in steam generation plant
