Sodium salts were used in the reduction roasting and magnetic separation process to separate and recover iron and manganese from the highiron manganese
In this study, a process to separate manganese and iron from manganiferous iron ores by reductive acid leaching followed by magnetic separation was
Introduction. As an important nonferrous metal and a national strategic reserve resource, manganese is widely used as deoxidizer, desulfurizer or as an alloy
Abstract In this study, the use of XRF, XRD and other instruments found that the manganese content in the ore was 14.53%, and the main forms were carbonate,
In allusion to study of complex iron, manganese polymetallic ore,Fe has a grade of 14.28% while Mn 18.72% in the raw ore.According to process mineral
Among the explored manganese oxide ore resources in China, there are beyond 37.5% with the manganesetoiron mass ratio being less than 3, and ten millions of manganese with
The second strategy involved a blend process of the ElGedida highMn iron ore with the Um Bogma manganese ore. The magnetic separation failed to reduce the

The separation of manganese and iron from a manganiferous iron ore using horse dung (biomass) as reductant was investigated in a sulfuric acid solution, and 99.80% Mn and 17.76% Fe were extracted into the solution under these leaching conditions: 1 M sulphuric acid concentration, 120 g/L biomass, 1/10 solid to liquid ratio, 300 rev/min
In this study, a process to separate manganese and iron from manganiferous iron ores by reductive acid leaching followed by magnetic separation was conceived and experimentally tested. In the leaching process, sulfuric acid was used as lixiviant and oxalic acid was used as reductant. The experimental results showed that the
Sodium salts were used in the reduction roasting and magnetic separation process to separate and recover iron and manganese from the highiron manganese oxide ores to utilize the complex ores. Results showed that Na 2
Introduction. Iron and manganese are important alloy metals that are widely used. Of these, 90% of manganese ore resources are used in the iron and steel industry in the form of manganese ferroalloy and electrolytic metal manganese products, and the remaining 10% of manganese ore resources are used in fertilizers, feeds, and the
Manganese (Mn) extraction from ironrich pyrolusite ore with cheap sulphur dioxide is considered to be the most promising method with advantages of rapid leaching rate and high leaching efficiency. Nevertheless, codissolution of iron (Fe) with manganese has limited the development of its commercial practice. In this work, the
The applicability of concept was validated using ferruginous manganese ores. Mineralogical characterization and magnetic separation studies were performed. XRD analysis has identified hematite and goethite as major iron minerals of ore. Manganese is contributed by pyrolusite and brinesite along with kaolinite and quartz as gangue minerals.
The PLS containing 35.07 g/L zinc, 3.16 g/L iron, and 4.58 g/L manganese impurities was produced. A special purification process including Fe precipitation and Zn solvent extraction was implemented.
ing layers of iron and manganese ore. The iron in such cases is generally in the larger quantities and the more continuous deposits; while the manganese is often represented by thin len It might be supposed that a separation could be produced by secondary concentration such as segregation, replacement, etc. This has doubtless
Furthermore, it was observed that the liberation of manganese mineral was in a course size range, i.e., 300 to 450 µm, while the association of iron and manganese bearing phases was lower in
Abstract. The carbon reduction of manganese of in the multicomponent system MnO–Fe 2 O 3 –CaO–SiO 2 –MgO–Al 2 O 3 in a liquidphase state is subjected to thermodynamic modeling. This system is an oxide mixture, which is close to the compositions of manganese ore, and a highcarbon ferromanganese slag at mass ratios

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were
