Iron ore pellet properties under simulated blast furnace Jultika Jun 9, 2017 A blast furnace is the dominant process for making iron in the world Iron ore pellets are commonly used as iron burden materials in a blast furnace, in which iron oxides are reduced to metallic molten iron.
Iron ore pellets are spheres of typically 6-16 mm (024-063 in) to be used as raw material for blast furnacThey typically contain 64%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets Typically limestone, dolomite and olivine is added and Bentonite is used as binder The process of pelletizing combines mixing of.
Iron ore pelletization Allied Colloids Limited Aug 04, 1987 Iron ore needs to be in the form of agglomerates of substantial size when it is charged into a blast furnace If the available ore is in the form of particles that are too small for direct feed to the blast furnace it is.
the iron content, but also the agglomeration processes to achieve a homogeneous material s size that could ensure a suitable operation in the furnace Until the 1950s of the last century, oxidized iron ores with a granulometry within 10 and 120 mm were loaded into the blast furnace (lower sizes led to permeability problems in the furnace bed) [3].
Apr 25, 2018· Pelletization is the standard method of agglomerating used to turn fine minerals fractions, mainly of iron ore, into an adequate product (pellet) to be fed to the blast furnace and to the direct reduction reactors The present invention describes the use of a binder composition comprising a colloid agent and a synthetic polymer.
