At present approximately 40,000 tons ilmenite, 25000 tons rutile and 1200 tons zircon are produced. In the international market they fetch $240, $1700 and $ 1900 per ton respectively. We now have 565 workers in our factory. To keep them occupied we need 240,000 metric tons of sand to get these minerals.
