Kazakhstan's Kazatomprom, the world's biggest uranium miner, reported a nearly sevenfold year-on-year increase in third-quarter profit on Friday as its physical sales volume doubled in the same period.

According to the company's financial report, its quarterly profit stood at 138.9-billion tenge ($299-million), up from 20.8-billion tenge a year ago. Revenue tripled in the quarter to 285.8-billion tenge ($615-million).

The company said in an earlier operations report the surge in sales was largely owing to the schedule of customer deliveries.
