May 12, 2016· In this study, a method for preparing pure manganese sulfate from low-grade ores with a granule mean size of 0.47 mm by direct acid leaching was developed. The effects of the types of leaching agents, sulfuric acid concentration, reaction temperature, and agitation rate on the leaching efficiency of manganese were investigated. We observed that sulfuric acid …
Jan 01, 1982· The dissolution of manganese from low-grade manganese oxide ore by ferrous sulphate may involve at least three steps in series: (1) Diffusion of FeSO4 from the main bulk of the liquid through the bound- ary layer to the active sites, i.e. to manganese-bearing mineral grains. (2) The nucleation of products at the active sites.

Among them, the direct leaching method includes the hydrosulfite method, sulfur dioxide method, ferrous sulfate method and so on. Taking the leaching method of sulfur dioxide for manganese as an example, the manganese ore is slurried, and sulfur dioxide gas is introduced, and the manganese oxide in the ore is converted into MnSO4 and MnS2O6.

Jan 09, 2010· Kosak et al. have suggested that when a mixture of ferrous sulfate, zinc sulfate and manganese sulfate is reacted with tetramethyl ammonium hydroxide in a microemulsion medium in the pH range of 4.1–13, the resultant powder is mostly α-FeOOH (goethite) at pH ~8 whereas the manganese zinc ferrite spinel phase appeared at pH values above 8 ...
When an aqueous suspension of pyrite and manganese ore reacts with oxygen, manganese is dissolved by the ferrous sulphate and sulphuric acid produced by the oxidation of pyrite. The kinetics of certain steps in the overall reaction were studied. A rate equation for the oxidation of ferrous sulphate by gaseous oxygen was derived for the temperature range from 1000 to 200 C.
It is obtained by reacting manganese compounds with sulfuric acid. It is also obtained as a byproduct in the manufacture of hydroquinone. Other manufacturing processes include the action of sulfur dioxide on a slurry of manganese dioxide in sulfuric acid, and the roasting of pyrolusite (MnO 2) ore with solid ferrous sulfate and coal, followed ...
