Industrial development worldwide is mainly dependent on one metal, i.e., iron. Metallic iron is extracted from ores of iron found as mineral deposits in different parts of the world. Iron ore is, therefore, the main component for obtaining metallic iron. For the steel-making process, iron ore is first converted into pig iron, which is further used to manufacture steel.

Siderite is a common authigenic cement found in sedimentary rocks and its formation is usually attributed to shallow (centimetre to a few hundreds of metres) sub-surface processes occurring during rock diagenesis (Liu et al., 1997; Larrasoaña et al., 2007; Lin et al., 2020). However, it is thought to also form at greater depths.

What is Siderite? Siderite forms three solid-state solution series. It's the iron (Fe) analogue in a series with manganese (Mn) dominant rhodochrosite. It also forms the Fe-end of a series with zinc (Zn) dominant smithsonite, as well as with magnesium (Mg) dominant magnesite. Siderite has been used as an iron ore and for steel production.
