Read More2021-5-7 Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore

Read More2015-1-1 The main difficulty in processing and utilization of low-grade iron ores primarily stems from their mineralogical characteristics as well as the soft nature of some ores and their high silica content. Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today.
Read More2020-6-15 It can be seen from Fig. 3(a), (b) and (c) that with a increase in the roasting temperature, iron grade and iron recovery, manganese grade, bivalent manganese and manganese reduction degree all showed the trend of increasing first and then decreasing. With the increase of roasting temperature, hematite in the ore was gradually converted to low valence iron oxide, pyrolusite was gradually converted to low valence manganese oxide, which promoted the improvement in iron and manganese grade
