The Northern Territory government says it will send a trade mission to India, after the federal Labor Party lifted a ban on selling uranium to the Asian nation.

NT Chief Minister Paul Henderson has wasted little time in announcing the move to promote trade and investment.

The Northern Territory is home to the Ranger mine, which produces about eight per cent of the world's mined uranium, about 260km east of Darwin.

Another large uranium resource, known as the Jabiluka deposit, is located 22km from Ranger but is not being mined due to opposition from the local Aboriginal people.

Delegates to the ALP's national conference on the weekend voted narrowly in favour of lifting the ban on selling uranium to India, a nation that has not signed the Nuclear Non-Proliferation Treaty.

India has some domestic uranium resources but not enough is mined to supply both its weapons and energy programs.

Mr Henderson said the federal government had deemed it safe to sell uranium to the world's biggest democracy.

"India has committed to our uranium only being used in terms of its energy production cycle not its other weapons' cycle," he told ABC radio.

Australia has the world's largest known uranium reserves.
