Sintering and pelletizing upgrades the manganese content of the ore through the loss of oxygen from manganese oxides and other volatile species as bound water and carbonates. An example of nonfluxed and fluxed compositions of agglomerates is shown in Table 7.4 ( Gasik, 1992, Kutsyn et al., 2011 ).


The sintering process is beneficial as it drives off any surface or chemically-bound water, decomposes the carbonates in the ore (calcination), and achieves reduction of manganese minerals to Mn2O 3 [2] while simultaneously agglomerating the ore fines into larger particles with suitable compressive strength for charging to smelters.


To determine the optimal process conditions the method of mathematical planning of experiments is used. It has been found that an increase in manganese ore in the sintering mixture contributes to the strength of the sinter, and increase in coal mining waste reduces the strength of the sinter.

Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become "agglomerated"). "The mines produce a ...


NOx, Hg 0 and VOCs are the major atmospheric pollutants produced in the sintering process, which cause serious harm to human health and the ecological environment. In this study, the simultaneous selective catalytic oxidation (SCO) of NO, Hg 0 and toluene from sintering flue gas by the natural ferrous manganese ore was investigated in a fixed bed reactor.


A process for sintering manganese ore was developed by Outokumpu with equipment proven in the sintering of chromite . In the process, manganese ore fines are micro-pelletised and/or nodulised, sintered on a steel belt and then crushed to the proper size.


After beneficiation sintering / pelletization of iron ore, beneficiation and sintering of manganese ore fines attracted technology experts due to massive expansion in manganese based ferro-alloys. Fast depleting high grade lumpy manganese ore deposits made the beneficiation and sintering all the more wanted solution.


10%The use of methane for reducing manganese ore has been studied for several decades. Both pure manganese oxide and manganese ore have shown a two-stage reduction process in a methane-containing atmosphere. In the first stage, high-order manganese oxides are reduced to MnO by H 2 produced in self-decomposition of CH 4.


Reduction roasting of manganese ore is the first step in the extraction of the metal, production of manganese based chemicals and benefaction of ferruginous manganese ores. In comparison to the conventional processes, the invented process replaces the expensive petroleum based reductant injected with air by cheap solid carbonaceous material and sealing of air entry.
