Sterlite Industries (India) Limited - Sterlite Industries India Ltd.

consists of a 400,000 tpa copper smelter, a 205,000 tpa copper refinery, a 90,000 tpa copper rod plant, a 1,300,000 tpa sulphuric acid plant, a
230,000 tpa phosphoric acid plant, a 700 tpa doré anode plant and two captive power plants with capacities of 22.5MW and 24.0MW,
respectively.
The captive power plants with a total capacity of 46.5MW, together with a further 11.2 MW generated from the smelter waste heat boiler,
meet most of the facility’s power requirements. The remaining power requirements of the facility, which amount to approximately 22.5% of its
total power requirements in fiscal 2009, are obtained from the state power grid. Our captive power plants at Tuticorin operate on low sulphur
heavy stock procured through long-term contracts with various oil companies.
The smelter at the Tuticorin facility utilizes IsaSmelt TM furnace technology. The refinery uses IsaProcess TM technology to produce copper
cathode and the copper rod plant uses Properzi Continuously Cast and Rolled, or CCR, copper rod technology from Continuus-Properzi S.p.A.,
Italy, to produce copper rods.
Silvassa
Our Silvassa facility, established in 1997, is located approximately 140 kilometers from Mumbai in the union territory of Dadra and Nagar
Haveli in Western India. Our Silvassa facility currently consists of a 195,000 tpa copper refinery and two copper rod plants with a total
installed capacity of 150,000 tpa of copper rods. Its refinery uses IsaProcess TM technology in the production of copper cathode and its copper
rod plants use Properzi CCR copper rod technology. Our Silvassa facility draws on the state power grid to satisfy its power requirements.
Fujairah
Fujairah Gold FZE is located in the Fujairah Free Zone-2. Our Fujairah facility is strategically located 130 kilometers east of Dubai and is
on the coast of the Arabian Sea. Fujairah Gold FZE recently completed its precious metal refinery project at a cost of $5.2 million. The
precious metal refinery was commissioned in March 2009 and began production in April 2009, with a capacity of 20 tons of gold and 85 tons
of silver. Outotec oyj, Finland, the pioneer in providing technology for extraction and refining of precious metals, supplied the technology for
the precious metal refinery. Fujairah Gold FZE is also executing a copper rods project at its Fujairah facility, which is expected to be completed
by the end of 2009 with a capacity of 100,000 tpa. Continuus Properzi S.p.A., Italy, is supplying the rod mill equipment for this project, and the
copper cathode required for the copper rod plant is expected to be sourced from the smelters of the Vedanta group.

Notes:
(1) Copper anode is an intermediate product produced by copper smelters and is not sold to customers. It is used for the production of
copper cathode by copper refineries. Approximately one ton of copper anode is required for the production of one ton of copper
cathode.
(2) Sulphuric acid is used as a starting material for phosphoric acid. Approximately 2.8 tons of sulphuric acid are required for the
production of one ton of phosphoric acid.
(3) Copper cathode is used as a starting material for copper rods. Approximately one ton of copper cathode is required for the production of
one ton of copper rods.
