A-Z Guide to Screening Ore, Rock & Aggregate. A simple definition of a "screen" is a machine with surface(s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface".
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 ...

Iron ore pellets are spheres of typically 8–18 mm (0.31–0.71 in) to be used as raw material for blast furnaces. They typically contain 67%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolostone and olivine is added and Bentonite is used as binder.
