Leading Zinc producer Hindustan Zinc is all set to commission two new mills in Rajasthan with a joint capacity of 3 million tonnes of ore-treatment with an investment of Rs 600 crore. The first mill of 1.5 million tonne is being commissioned at Zawar mines, about 45 km away from Udaipur. Zawar’s current ore treatment capacity is 2.5 million tonnes, and post setting up of new mill of 1.5 million tonnes, the ore treatment capacities would increase to 4 million tonnes. Zawar has 4 mines with combined ore production capacity of 4 million tonnes which is being expanded to 8 million tonnes in the next 5 years through mechanisation and switching over to trackless mining.
The second mill of 1.5 million tonne is being commissioned at Sindesar Khurd mine in Rajsamand district in Rajasthan. Sindesar Khurd mine’s current ore
treatment capacity is 4.5 million tonnes, and post commissioning of new mill of
1.5 million tonnes would increase to
6 million tonnes.
Sindesar Khurd mine is known for its silver production and is the most mechanized mine in India. The ore production at silver rich Sindesar Khurd mine is being expanded from the current capacity of 4.5 million tonnes to 6 million tonnes.
Both the new mills are expected to be commissioned by Q3 of FY 2019.
After the commissioning of new mills, the ore treatment capacity will increase to 17.5 million tonnes from the current 14.5 million tonnes per annum.
Hindustan Zinc is expanding all its mines to meet the growing demand. Rajpura Dariba mine is being expanded to 1.5 million tonnes from the current capacity of 0.9 million tonnes. Zawar mine is all set to reach the capacity of 8 million tonnes in the next 5 years from current capacity of 4 million tonnes. The company’s Kayad mine in Ajmer has ore production capacity of 1 million tonnes and efforts are being made to expand this mine as well to 1.2 Mt.
Hindustan Zinc is transitioning to become a fully Under-Ground Mining Company by FY 2019.
Rampura Agucha Mine of the Company, the world’s second largest zinc producing mine and responsible for 75 per cent of company’s total output and also the only open-cast mine in the portfolio, is gradually moving to underground mine operations. The 955 meters depth shaft sinking work at Rampura Agucha Mine has already been completed and the development muck is in progress. The Shaft is likely to be commissioned by Q3 of FY 2019. The shaft sinking work at Sindesar Khurd mine has already been completed and commissioned and the shaft has reached a depth of 1050 meters.
After the commissioning of new mills, the ore treatment capacity will increase to 14.7 million tonnes from the current 11 million tonnes per annum.
The CEO of Hindustan Zinc, Sunil Duggal informed that, “Setting up of new mills is part of our plan to match growing demand of Zinc in India. With +3 million tonnes of additional treatment of ore, we would be able to increase substantial volume of metal. We are on our course to produce 1.2 million tonnes of metal and moving steadily to produce 1.5 million tonnes. We are investing close to Rs 600 crore to set up these two new mills. Our Fumer Plant is also on track for commissioning soon. This will give us technology to extract Lead and Silver from waste”
The company is also setting up Fumer Plant to further improve recovery of metals from the slag which will also boost its metal production, particularly Lead-Silver with an investment of Rs 570 crore. The company has plans to put-up three Fumer plants overall at its locations in Rajasthan.
In the year 2016-17 Rampura Agucha mine produced ore both from open-cast and under-ground mine. The contribution of open-cast was 3.3 million tonnes and under-ground as 1.4 million tonnes. Rampura Agucha mine ore production capacity is expected to reach about 4.5 million tonnes by 2019-20, which was 6.15 million tonnes as on 31st March 2017.
Though ore production capacity of all the mines put together is 12.20 Mtpa, the actual ore production in the year 2016-17 was 11.87 million tonnes. The company is aiming to expand the mine production levels to 13.10 mtpa in the current financial year and reaching to 17.50 mtpa by FY 2020.
