The flux of dissolved Fe (Fe d) from sediments is a critical component of the biogeochemical Fe cyclemon approaches to estimating these fluxes are based on modeling of Fe d porewater profiles or incubating sediment and overlying water using benthic chambers or retrieved cores. Inadequate resolution of pore water Fe profiles in …
Iron plaque is known to concentrate trace elements, especially As; As(V) is the predominant species, followed by As(III) and minor amounts of dimethylarsinic acid (Seyfferth et al., 2010). The concentrations of As and Fe in Fe plaque are positively correlated ( Pan et al., 2014 ), and Fe-plaque-sorbed As accounts for most (> 70%) of …
Manganese (Mn) extraction from iron-rich 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, co-dissolution of iron (Fe) with manganese has limited the development of its commercial practice. In this work, the separation …
Understanding how seeds obtain and store nutrients is key to developing crops with higher agronomic and nutritional value. We have uncovered unique patterns of micronutrient localization in seeds using synchrotron X-ray fluorescence (SXRF). Although all four members of the Arabidopsis thaliana Mn-CD …

In groundwater applications, plant design will be the same as for simple iron removal (figures 22 and 23); whether the water contains manganese only or manganese and iron, the first step will be an aeration (gravity or …
Too low of a temperature will reduce the reduction efficiency, resulting in poor separation of iron and manganese. The SMR was carried out with a total gas-flow rate of 600 mL/min (N 2 480 mL/min, H 2 120 mL/min). The influence of temperature on the total iron and total manganese indexes of the magnetic separation products is shown in Fig. 2.
Sodium salts were used in the reduction roasting and magnetic separation process to separate and recover iron and manganese from the high-iron manganese oxide ores to utilize the complex ores. …
In this study, a process to separate manganese and iron from manganiferous iron ores by reductive acid leaching followed by magnetic separation was conceived …

Abstract: A large number of studies have shown that oolitic hematite is an iron ore that is extremely difficult to utilize because of its fine disseminated particle size, high harmful impurity content and oolitic structure. To recover iron from oolitic hematite, we developed a novel multistage dynamic magnetizing roasting technology. Compared with traditional …
Sodium salts were used in the reduction roasting and magnetic separation process to separate and recover iron and manganese from the high-iron manganese oxide ores to utilize the complex ores. Results showed that Na 2 S 2 O 3 was the most effective salt.
Table 1 demonstrated that the total iron content in the ore was 47.96%, total manganese content 15.8%, and divalent manganese content 0.92%. In addition, the contents of Al 2 O 3, MgO, and CaO were 1.18%, 0.22%, and 0.06% respectively.Meanwhile, the contents of penalty elements P and S were 0.016% and …
Larger cracks promoted adsorption of flotation reagents and the separation between iron mineral and P-bearing mineral. Therefore, this innovation contributes to improving the magnetism of weakly magnetic iron ore and enhances the separation effect of Fe extraction and dephosphorization. It has good industrial application potential.
