Siderite Ironrich Deposits-HN Mining Machinery Manufacturer

Iron ore deposits associated with Hormuz evaporitic series . Apr 01, 2019 Hematite as specularite and oligist is the major mineral in the iron-rich bands with minor goethite, pyrite, magnetite and rare siderite. Textural relationships between the ore and gangue minerals indicate that these ores are Rapitan-type sedimentary banded iron deposits.

Iron-rich sedimentary rocks - Wikipedia

However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 539 million years ago), the early Paleozoic (539 to 419 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).

The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996 ), distinctively different from that of pyrrhotite ( Section 5.08.3.9 ). Siderite is paramagnetic at ordinary temperatures and carries no NRM.
