Dec 28, 2015· Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, Michigan in ...

The most commonly employed agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets). Figure 1: Iron pellets . The pelletizing process is a process which contains numerous sub-processes, or process segments.

When applying the results in balling of iron ore, the differences in agglomeration conditions should be recognized. Industrial iron ore green pellets are over-saturated and a supporting network of viscous liquid is formed on the green-pellet surface . The strength of this network is initially controlled by the viscosity of the liquid phase.

Composite agglomeration process (CAP) of iron ore fines has been proved an effective route for ironmaking burden production, and is characterized by low the fuel consumption and high the productivity compared with the traditional sintering process. Sintering behavior of pelletizing feed in CAP has not been studied fully yet.

Agglomeration processes combine small, discrete particles into larger aggregates, where the individual particles are still discernible (Ennis and Litster 1997). During iron ore agglomeration or pelletization, moist iron concentrate particles and flux materials are rolled into balls with the aid of a binder (Figure 1).

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...

The decline in the availability of high-grade iron ore has driven the development of fine particle agglomeration processes to meet the demands of blast furnaces. The diminishing number of high-grade ore deposits also led to the mining of lower-grade deposits, including taconite deposits that had previously been ignored.
