Bailadila

BAILADILA (RU: Байладила) is the iron ore belt at the east of India (Madhya Pradesh state, Bastar district). There have been identified within its limits the largest (14) deposits of the high-grade (more than 63% of Fe) hematitic ores, which are situated within the mountains at the height of 1200-1250 metres. The exploration has started during the 1958, the development proceeds since the 1967. The ore bodies are associated with the two parallel ridges, which are stretching along the meridional direction, and are confined to the synclines, which have been formed by the metamorphic rocks of the Proterozoic. The sizes of the ore bodies mainly range from 900 to 1500 metres of length, and from 200 to 500 metres of width; the thickness is usually 30-60 metres, sometimes up to 150 metres.

The rich ores are associated with the rocks of the Bailadila series (the Lower Proterozoic), which, according to their origin, belong to the residual rich ores, which are associated with the ferruginous quartzites. The bedrock ore bodies (massive hematitic, less often layered magnetite-martite-hematitic and powdered ores) are usually covered by the lateritic ores. At the bottoms of the ore-bearing stratum, there are developed the small ore bodies, which are formed by magnetite and martite. The thickness of the ore-bearing layer is 300-400 metres. The reserves of the conditional (63-67% of Fe) ores are estimated according to 14 deposits at 1.3 billion tonnes; the resources of the rich hematitic ores exceed 3 billion tonnes. There is being developed by the open pit method the deposit # 14 (since the 1968); its proven reserves are estimated at 150 million tonnes of ore. The deposit # 5 has started being developed since the 1977. These two open pit mines are the highly mechanized modern enterprises. The productivity of the open pit mines at the deposits # 14 and # 5 amounts to 5.5 million tonnes of the marketable ore, including the 5.1 million tonnes of the lump one, and 0.4 million tonnes of the ore fines (1980); in the future, up to 10 million tonnes of the ore per year. The ore, which has been extracted, is subject to the crushing and screening. The ore fines are being stockpiled (approximately 1-2.5 million tonnes per year). The marketable produce is exported to Japan through the Visakhapatnam port.
