JSW Steel shares jumped as much as 4.47% on optimism that iron ore will be more easily available to the company after India raised export duty on the steel making raw material to 30% from 20%

The country's highest court in August put an interim ban on iron ore mining in Bellary district of Karnataka, forcing the company to run its plants at lower capacity.

Mr Hiten Gala senior manager advisory at brokerage Sharekhan said that "Iron-ore producers will now prefer domestic customers rather then exporting, due to higher taxes.”
