Iron-rich sedimentary rocks are sedimentary rocks which contain 15 wt.% or more iron.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 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).

The role of siderite in Phanerozoic and Precambrian iron formations is discussed. Various types of iron formations are characterized, and their place in the evolution of sedimentary iron ore deposition is outlined. In Precambrian iron ore deposition, siderite is a primary mineral, whereas in Phanerozoic iron formations it becomes a secondary mineral and is commonly related to diagenetic and

A difference in the mechanisms of the metallization of crude ore and the roasted concentrate is observed. The metallization of roasted concentrate lumps is more efficient than that of crude siderite ore. In this case, the process ends earlier and can be carried out at higher temperatures (1250-1300C) without danger of skull formation.

Oct 04, 2011An enrichment technology for reduced siderite ore has been developed for the production of concentrate that may be used in steel smelting. The technology includes dry and wet magnetic separation. Conditioned briquets may be produced from reduced siderite-ore concentrate and used in arc furnaces as a partial or complete replacement for scrap or hot metal.

Spathic iron ore. Although spathic (carbonate) iron ores, such as siderite, have been economically important for steel production, they are far from ideal as an ore.. Their hydrothermal mineralisation tends to form them as small ore lenses, often following steeply dipping bedding planes. This makes them not amenable to opencast working, and increases the cost of working them by mining with
