Siderite

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος sideros, iron. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series. Get price

Iron

Iron-rich sedimentary rocks are sedimentary rocks which contain 15% 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).

An Introduction to Iron Smelting

May 20, 2017Iron ore comes in the form of rocks or other sediments. These are composed of iron oxides, which we try to reduce, and the unwanted 'gangue materials' which take the form of silicates and alumina, in other words the 'rock' part of the ore. Besides oxides, which are oxidised iron, iron ore also occurs in the form of sulphites and carbonates. Get price
