Effect of limestone and dolomite flux on the quality of

Oct 23, 2020 A combination of limestone and dolomite is recommended as a suitable fluxing agent for the preparation of iron ore fluxed pellets. Thermogravimetric studies of the pellet feed materials were indicative of the thermal decomposition of LOI contributing mineral phases: goethite at 300 °C, kaolinite at 470 °C, limestone, and dolomite at 700–750

Effect of limestone and dolomite flux on the quality of

Self-binding properties of the ore ensured the complete elimination of external binder. • LOI acts as a promotor for the formation of binding phases when fluxing agents of limestone and dolomite are used. • Optimized use of limestone–dolomite (1:1) improved the physical and metallurgical properties of the fluxed pellets.

Iron ore pelletizing TON Outotec

Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help

Effect of fluxing agents on reduction degradation

Apr 06, 2016 During induration at a high temperature, a considerable amount of slag/melt phase forms inside the iron ore pellets, comprising SiO2, Al2O3, CaO, MgO and FeO. After cooling, the slag phase solidifies and acts as an important bonding phase in the finished pellets and influences their room temperature as well as high temperature properties, especially reduction degradation.

Limestone and Dolomite and their Use in Iron and Steel

May 08, 2013 Dolomite in iron and steel industry is normally used in three forms. These are (i) raw dolomite which is also the natural form of dolomite, (ii) calcined dolomite, and (iii) sintered dolomite. When dolomite is used as a fluxing material then it is used as either raw dolomite or calcined dolomite.

Flux (metallurgy) Wikipedia

In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.
