Parrikar said almost 10 per cent of the ore lying in these dumps could be exported.
Goa government has decided to levy a fee of Rs 120 per square of land occupied by the rejected iron ore dumps in private areas while Rs 220 per square metre would be charged for those on revenue land.
Such a policy would ensure that iron ore dumps lying idle are linked to the mining lease and only mining lease-holders are able to apply for conversion of the land to ensure that the ore can be accounted for.
The state government expects to earn revenue of Rs 300 crore from this initiative, he claimed.
