Magnetic properties of oolitic iron ore on Bell Island
网页The other iron-bearing minerals identified are siderite and chamosite. Microscope observations of thin sections suggest that the rocks consist of oolitic hematite in a matrix of siderite or calcite. The intensity of natural remanent magnetization (NRM) varies in the range of (0.03–0.4 A m−1), depending on the percentage of hematite.

Hematite: Properties, Uses, DistributionSolved
网页Ans. Hematite and Siderite are the ores that come from Iron. Hematite contributes 37% of ore and siderite contributes very less as it is low-grade iron ore. Hematite ore consists of 60 to 70% of iron ore which has a redbrown colour. It is known for its finest quality. The Siderite is a brown colour that has 48% iron with impurities.
