    2013-7-3  Siderite, that is iron carbonate, is naturally low-grade in Fe even if the mineral content in the ore may be high. Common processing started with calcination to drive off CO 2, followed by low-intensity magnetic separation as the FeCO 3 was more or less converted to magnetite, Fe 3 O 4. The processing sometimes had detrimental consequences, such as spreading arsenic and lead through stack gases
