Faced with the …
The "ore group" iron ore textural classification scheme (Table 2.7 and Figures 2.7 and 2.8) has been developed to link ore texture to downstream processing performance including lump/fines ratio, beneficiation, blast furnace lump physical and metallurgical properties, or fine ore sintering quality (Clout, 2002). The Ore Group …
The ores are mainly hematite, with TFe content more than 50%. In China, the BIF-related iron deposits are the most important type of iron deposits, accounting for approximately 64% of the total identified resources. However, most of them are low-grade iron ores (in China, the low-grade iron ore is defined as 20% ≤ TFe < 50%, and the iron …

Natural iron is a mixture of four stable isotopes: iron-56 (91.66 percent), iron-54 (5.82 percent), iron-57 (2.19 percent), and iron-58 (0.33 percent). Iron compounds are amenable to study by taking advantage of a phenomenon known as the Möss effect (the phenomenon of a gamma ray being absorbed and reradiated by a nucleus without …
Additionally, studies have shown that Mengku iron ore has strong remanence; the ratio between the induced magnetization and remanence is about 2.3 and the average residual ratio of its surrounding ...
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.
