Chhattisgarh accounts for about one-fifth of India's iron ore reserves and the race to extract that is driving deforestation in the state. According to the Chhattisgarh forest department, about 4,920 hectares of forest land has been diverted for iron ore mining projects over the years.

In July the iron ore price rose sharply from US$160/t to US$230/t before retracing just as quickly to US$160/t. While a retracement was widely expected, and despite the metal's volatile "boom/bust" history, Morgan Stanley acknowledges being somewhat surprised by how fast this occurred. The latest price response came amidst concerns that China ...

Introduction to Iron Ore Deposits: Rich iron ore deposits of high grade where the iron percentage is more than 60 per cent, eastern India account for more than half of the total current annual production of more than 180 million metric tonnes ...

Of the iron ore exported 38.5% of the volume was iron ore pellets with a value of $2.3 billion and 61.5% was iron ore concentrates with a value of $2.3 billion. Forty-six per cent of Canada's iron ore comes from the Iron Ore Company of Canada mine, in Labrador City, Newfoundland, with secondary sources including, the Mary River Mine, Nunavut.

The Iron ore price rose on Thursday, buoyed by hopes of a pick-up in steel demand in China. China's success in stamping out its covid-19 outbreak …

Current models for the origin of banded iron-formation (BIF) derived in situ iron ore deposits assume that the typical chert and iron oxide banded BIF is the primary rock from which enriched iron ore deposits arise by the selective leaching of quartz and the residual accumulation of the iron oxides. Weathering extends to the base of all the hematite deposits of the Hamersley Province, which ...

Medium- and lower-grade iron ore zones, comprising conglomeratic and brecciated ore, are preserved within deep palaeosinkhole structures on the southern portions of the deposit, where these structures are the result of karstification of the underlying dolomites during periods of uplift and erosion.
