Name of Mineral Iron Ore. Iron ore deposits of Chhattisgarh are associated with the rocks that are world over known to contain high grade ores i.e. Banded Iron Formation.

the ore is usually of the specular variety, and it is apt to be partly magnetite. The most important hematite deposits are of a sedimentary origin, the ore forming beds in stratified rocks. The hematite beds of the Wabana Mines, Newfoundland, extend for miles under the ocean. They are found in sandstone and shale of Ordovician age. In Nova Scotia, smaller deposits have been found in Devonian and Silurian stratified rocks. The hematite deposits of the Lake Superior region are of sedimentary origin, but the rich ores have undergone natural concentration from the lean ores of the iron formation. These formations are widespread in eastern Canada... 2. the leaching out of the silica, leaving the concentrated ore in place, as in the Mesabi and other Minnesota ranges and in Labrador. Only one deposit of the second kind has so far been found in Ontario, that at Loon Lake, east of Port Arthur. In the United States, they have been found mostly in hilly regions and toward the bottom of the slopes. Another common condition is a tight trough, or basin, formed by the iron formation and an intruding dike. Important ore bodies have been found that were completely without, or almost without, outcrop, in some cases being covered by slate. The hematite is sometimes mixed with enough magnetite to make possible a discovery by means of a magnetic survey. All varieties of hematite become... such gossan has occasionally been used as an iron ore. At Bannockburn, in the Madoc area, a pyrite deposit was discovered below the limonite, which was being mined as an iron ore; this gossan capping of the pyrite was from eight to fifteen feet deep. In the old iron mines near Londonderry, Nova Scotia, the ore was limonite in fissures originally filled with siderite and other carbonates. Limonite varies a great deal in its appearance. In color, it may be li... the quantity around the Helen Mine is estimated at not less than 100 million tons; the ore is high in sulphur, owing to the presence of pyrite, and requires to be roasted to remove sulphur as well as to remove carbon dioxide.
