Magnetization roasting is one of the most effective way of utilizing low-grade refractory iron ore. However, the reduction roasting of siderite (FeCO3) generates weakly magnetic wüstite, thus reducing iron recovery via weak magnetic separation. We systematically studied and proposed the fluidized preoxidation-low-temperature …

Siderite is one of the common iron ores. The iron grade of siderite (FeCO 3) is low, and the theoretical iron grade is only 48.20%.Some of them also contain Mg and Mn. Moreover, siderite is weakly magnetic iron ore, most of the siderites are fine-grained and complex in composition, and belong to refractory iron ore resources.

In sedimentary iron formations, siderite is the most abundant. In some cases, there are all grounds to sug-gest that siderite is the primary mineral whose deposition predetermined the subsequent course of iron ore deposi-tion. Without reconstruction of siderite deposition, our knowledge on iron ore genesis remains incomplete.

Weathering of Iron-Rich Minerals: Goethite often forms as a weathering product of other iron-bearing minerals, such as pyrite (iron sulfide), magnetite (iron oxide), and siderite (iron carbonate). These minerals can undergo oxidation and hydrolysis in the presence of water and oxygen, leading to the formation of goethite.
