Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature …
The sintering were carried out at 1135, 1140 and 1145°C during 7200 and 14400s under an argon atmosphere. The sintered products were characterized by BET surface area, apparent density, X-ray diffraction, MO and SEM/EDS.

The invention discloses a sintering process of manganese ore powder. The process comprises the following steps of: adding water to mix manganese ore powder, a binding agent, fuel, a fluxing agent and return ore as mixed ore, wherein the binding agent is formed by mixing manganese salt and organic matter and counts for 0.6-3.0% of mass …
Abstract. Pre-reduction of manganese ores by solid carbon was investigated to try to increase the efficiency and cost effectiveness of the ferromanganese industry. The pre-reduction reactions of ...
Crushed and screened ore may be concentrated by washing, sink-float, jigging, tabling, flotation, dense media separation and high intensity magnetic separation to produce a saleable concentrate. Carbonate manganese ores may be calcined. Higher-quality fines may be agglomerated, nodulised, sintered or pelletised.
Domestic Production and Use: Manganese ore containing 20% or more manganese has not been produced domestically since 1970. Manganese ore was consumed mainly by six companies at seven facilities with plants principally in the Eastern and Midwestern States. Most ore consumption was related to steel production, either directly in pig iron …
Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. Historically, manganese is named for pyrolusite and other black minerals from the region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite.
The Manganese Ore prices are compiled from the pricing lists of various manufacturers and worldwide mining data. Prices are updated regularly and are solely for reference.
Due to the randomness of all factors influencing the sintering operation, a two-stepped procedure is proposed to find the best way of using stocked fines at a plant producing Fe-Mn alloys for the steelmaking industry. The approach is based on the following: (1) predict the result of the sintering operation by establishing the best multilinear regression …

The enrichment and sintering plant of the Industrial Complex of Moanda (CIM) enables the valorization of Mn-rich fines generated during the production of MMA and MMD ores. Thanks to the analysis of historical data of the sintering plant, a data-driven Digital Twin of the process was developed. The goal behind the development of this Digital ...
An integrative process of the simultaneous catalytic oxidation of NO, Hg0 and toluene from sintering flue gas by the natural ferrous manganese ore was studied in fixed bed reactor and in situ DRIFTS.
Once the fines are sintered, they then go to a blast furnace or an electric arc furnace, to smelt the manganese iron into manganese alloys.
Lina Hockaday, Senior Engineer in Pyrometallurgy at Mintek 's New Technology Group in South Africa, proposes that solar thermal reactors, able to reach temperatures up to 1200°C, could virtually eliminate emissions from processing manganese ore fines, by using solar sintering.
Manganese ore fines generated at Balaghat and Ukwa mines of MOIL were subjected to sintering studies at the R&D Centre of Paramount Sinters Pvt. Ltd.
Based on the above issues, anthracite has become the main substituting fuel for coke breeze in iron ore sintering due to its reasonable price 19, 20. When this substitution is made, the particle size of the anthracite needs to be controlled 21.
In this study, a sintered manganese ore was tested for 56 h in two pilot units of different size. The oxygen carrier worked well in the process, was easily fluidized, and did not exhibit any ...
