:: Xstrata Technology to Supply Third IsasmeltTM TSL Plant to Vedanta

Xstrata Technology’s ISASMELTTM top submerged lance (TSL) smelting technology has been chosen for its third smelter project in India, with a contract signed recently with Sterlite Industries (India) Limited, a subsidiary of Vedanta Resources plc (Sterlite).

Chief Executive Joe Pease said Xstrata Technology (XT) is providing a technology licence, engineering services and commissioning services for the Tuticorin copper smelter expansion project. This is third time Sterlite has chosen the ISASMELTTM technology for Tuticorin. The new furnace will complement an existing ISASMELTTM and will have capacity to treat over 1.5 million tonnes a year of concentrate to produce 400,000 tonnes per year of copper anodes.

The Sterlite metallurgical complex, in Tamil Nadu state near the southern tip of India, started operations with its first ISASMELTTM in 1996. Success of this installation led to a second plant in 2005, which is now followed by this expansion. Pease said “Sterlite’s success is testominy to their operating expertise, and to the inherent advantages of ISASMELTTM - low capital and operating cost, high gas capture, and a myriad of ‘small’design features to improve operations and maintenance life. Sterlite and Xstrata operators have worked closely together over many years to continually improve design and operating performance. This plant knowledge and close ongoing relationship with licensees is the distinguishing feature of XT’s technical package - we offer long term support from expert operators of the technology”.

A new copper refinery will also be constructed as part of the expansion project, with XT’s ISA PROCESSTM technology also being supplied under a separate agreement. The new refinery will be adjacent to the existing ISA PROCESSTM refinery.

Copper ISASMELTTM furnaces are operating in India, Australia, Belgium, China, Germany, Peru, the United States and Zambia and are currently processing more than 6 million tonnes of raw materials per annum. This number is increasing rapidly as new plants are under construction in Kazakhstan and Peru as well as India.
