Small quantity is also utilised for glass manufacture.
Copper ore : Copper has undoubtedly the widest application of all the non-ferrous metals. Its physical properties provide a combination of a number of extremely useful characters which have provided it with the high position it holds amongst the base metals. Copper ore occurrences have been observed at Thanewasna, Dubarpeth in Chandrapur district, Pular-Parsodi, Ranbori-Kolar-Tambekhani, Ranmangli, Kitari, Thutanbori, etc. in Nagpur district. Geological Survey of India has carried out the exploration work in the Thanewasna and Thutanbori areas of Chandrapur and Nagpur districts respectively and GSI has indicated total reserves of Copper ore to be of the order of 7.70 million tonnes with copper content ranging from 0.81 to 2.73%.
Gold : Gold is the basic metal of currency and coinage and so having a important high position in the metal group of minerals. The investigation for gold has been carried out in the State by Geological Survey of India . Detailed investigation carried out by GSI in the Parsori ( west block) of Nagpur district has indicated good potential which is subject to further detailed exploration.
Tungsten ore : Tungsten is a strategic mineral which is widely used in electrical and electronic industries. It has wide application in space technology, steel industry, etc. The tungsten ore occurs in Kuhi, Khobna, Agragaon, Ranbori, Kolari-Bhaori areas of Nagpur district. The reserves estimated for tungsten in the State is about 19.98 million tones. Geological Survey of India and Mineral Exploration Corp. Ltd. have carried out vigorous exploration work for tungsten in the above said localities.
Zinc Ore : Zinc is used in the various types of alloys, in manufacture of dry batteries, in textile industry, rubber industries, chemical and metallurgical industries etc. Zinc ore occurs in few localities of the State mostly in Nagpur district i.e. Anjani, Tambekhani, Kolari-Bhaori areas. The total reserves indicated by GSI in Nagpur district are abo;ut 8.27 million tonns with 5.4% Zn.
