摘要： A method for producing high-purity manganese sulfate monohydrate from a low-grade composition includes acquiring a primary leached manganese solution by adding sulfuric acid and a reductant to a low-grade manganese-containing composition and leaching manganese therefrom; acquiring a secondary leached manganese solution from which primary impurities have been eliminated by adding calcium hydroxide to the primary leached manganese solution; acquiring a tertiary leached manganese solution from which secondary impurities have been eliminated by adding sulfides to the secondary leached manganese solution; acquiring manganese oxide from precipitating manganese by using sodium hydroxide in the tertiary leached manganese solution so as to control the pH thereof; adding sulfuric acid to the manganese oxide and redissolving; and drying the redissolved manganese oxide and acquiring high-purity manganese sulfate monohydrate. Thus the present invention allows production of high-purity manganese sulfate monohydrate from a low-grade manganese-containing composition, for use as material for a secondary battery.

摘要： This method of obtaining an aqueous solution of metal values from an insoluble metal oxide is possible where the metal has a lower oxidation number in the solution than in the insoluble oxide, for example manganese (+2 and +4 respectively).The oxide, such as MnO.sub.2, is treated with hot mineral acid such as HCl in the presence of coal. After some hours, the liquid comes to contain most of the manganese as dissolved Mn(II) ion.

摘要： A process for preparing manganese sulfate solutions having reduced concentrations of potassium impurity is disclosed wherein a digestion mixture of a reduced manganese ore, a source of water soluble aluminum ions, a source of water soluble ferric ions and an aqueous acid solution is prepared, having a solution pH ranging from about 0.5 to about 3.5. The mixture is then digested at a temperature sufficient to produce a mixed digestion product comprising a liquid phase of a manganese sulfate solution and a solid phase of digested ore residue and a particulate complex salt by-product. The liquid phase of manganese sulfate solution is then recovered from the mixed digestion product. An additional feature of this process involves conducting the digestion of the digestion mixture in the presence of at least one complex salt of the general formula:MFe.sub.n Al.sub.3-n (SO.sub.4).sub.2 (OH).sub.6where M is Na.sup.+, K.sup.+ or NH.sub.4.sup.+ and n is a number ranging from about 1 to about 3.

摘要： Large proportion of available manganese ores contain high proportions of potassium. Electrolytic manganese dioxide (EMD) is manufactured from manganous sulphate obtained from naturally occuring manganese ores. Crystallographically EMD has to be essentially gamma phase and other phases, alpha and beta should be the bare minimum. High potassium content is, however, an obstruction in the way of getting gamma phase EMD. The present invention describes a method of making manganous sulphate solution with low level impurity of potassium from high potassium ores which comprises adding the reduced ore to spent electrolyte containing ferric ions and digesting same at pH 1-2 and temperature of 60.degree.-90.degree. C. for 1-4 hours, and thereafter again adding reduced ore to the digested product till pH is raised to 4-6.
