A two-year old ban on iron ore exports from Karnataka which has halved shipments from the world's No. 3 supplier will take centre stage at an industry gathering in Bangalore this week as pressure mounts to lift the restriction.
Following is a timeline of key developments in India's iron ore sector since Karnataka, the country's second-largest producer, introduced its shipments ban:

September -- Iron ore exports post their sharpest monthly fall in nearly two years after Karnataka's ban and slow China demand. Exports drop 47 percent from a year earlier to 3.03 million tonnes.
November 19 -- Karnataka's high court upholds the ban on exports.
