To reduce the proportion of high energy consumption and pollution processes such as sintering and pelletizing, and to make full use of the waste heat resources of steel plant, a lump ore pre-heating treatment is proposed. The mineralogical properties of mainstream lump iron ores were first analyzed using chemical analysis, XRD-Rietveld, BET testing and thermogravimetry. …

lump ore samples were reduced very slowly and the disinte-gration of lump ore samples was not obvious. The samples' average diameter (weighted average of particle size distribu-tion) decreased from 12.75 mm to 11.71 mm. In the second step, the reduction degree of lump ore samples still kept at low level, but RDBI-6.3 increased sharply. The ...

Iron ore is prepared for subsequent steps in three forms: as lump ore (6–30 mm size), pellets (9–16 mm), and sinter (15–25 mm). Lump ore is used when the ore grade is relatively high, and requires no processing except crushing and screening, although some simple separation such as washing of fine particles may be done.
