Mining company Vedanta Resources said mined metal production at its Indian zinc unit rose 42 per cent in the first half, boosted by higher ore production across all its mines.

The Rampura Agucha open pit-mine operator said Zinc India's mined metal production was 4,52,000 tonnes for the first half ended September 30.

The company, which mines zinc in Rajasthan, said integrated zinc production rose 54 per cent to 3,86,000 tonnes and integrated silver rose 30 per cent to 8.2 million ounces during the period.
