Siderite Wikipedia

Siderite is also the name of a type of iron meteorite.Siderite is a mineral composed of iron(II) carbonate (FeCO3). 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.

Siderite Mineral Properties, Photos and Occurence

Nov 22, 2018 Siderite is a member of calcite group minerals, which have a similar structure and form several solid-solution series. The miscibility of the calcite group members is limited though. Of the several possible members of the solid-solution series associated with siderite (FeCO 3), only the smithsonite (ZnCO 3), magnesite (MgCO 3) and rhodochrosite (MnCO 3) varieties are common.

CN1857783A Ore dressing process for siderite, limonite

The present invention relates to ore dressing process for siderite, limonite and other weak magnetic iron ore. Siderite, limonite or other weak magnetic iron ore is made to pass through the magnetizing and roasting, magnetically separating and reverse floating process in a rotary kiln to obtain concentrated iron ore with TFe 62-69% and recovering rate 78-88%.

Sustainable iron production from mineral iron carbonate

First published on 11th October 2016. The reduction of iron ores with hydrogen is considered a promising CO 2 breakthrough technology to mitigate CO 2 emissions from the iron and steel industry. The state-of-the-art production of iron and steel from mineral iron carbonates (FeCO 3) is based on the thermal decomposition of FeCO 3 in air to produce hematite (Fe 2 O 3) suitable for iron production.

Processes and Procedures in the Extraction of Iron

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
