Siderite – WGNHS – UW–Madison

Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides.

Synthesis of magnetite powder from the mixture consisting of siderite

The formation of magnetite started at 400 °C, resulting in magnetization increase. Both siderite and hematite transformed into magnetite, since two different Curie temperatures were recorded at cooling. The mixture consisting of siderite and hematite ores in equal proportion completely transformed into magnetite.
