Embodiment Construction
[0018] The present invention will be described in detail below, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0019] The production method of manganese sulfate electrolyte, it may further comprise the steps:
[0020] Firstly, the pyrolusite and pyrite raw materials are respectively ground into powders and then mixed in proportion in the roasting equipment for roasting. If the particle size of the ground ore powder is too large, the contact area of the two ores will be reduced and cannot be fully mixed. If the particle size of the ground ore powder is too small, it will be taken away by the air flow and cannot be roasted; generally, pyrolusite The particle size of the powder that is ground with pyrite is 150 mesh to 250 mesh. The roasting temperature is controlled at 560° C. to 620° C., and the roasting time is 3 to 4 hours.
[0021] Then, selectively leaching the ...

The invention relates to a production method of a manganese sulfate electrolytic solution. The production method comprises the steps that raw pyrolusite and a raw pyrite are ground into powder particles, mixed proportionally and roasted in roasting equipment; the roasted mixture is subjected to selective leaching, a manganese sulfate leaching solution is conveyed into a container and added with barium sulfide to be stirred and filtered; and filtrate obtained after filtering flows out from an inner cavity of an inner shaft and is subjected to three-stage purifying, supernatant is taken for electrolysis after filtering, and the manganese sulfate electrolytic solution is obtained. According to the production method, the manganese ore is subjected to sulphating roasting, sulfuric acid is not used during follow-up leaching, and thus, pollution to the environment is greatly relieved while the production cost is reduced; and meanwhile, the solution is filtered by the inner shaft and an outer shaft which are used for driving a stirring rod to rotate, stirring and filtering are achieved without other auxiliary equipment, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the preparation of manganese sulfate electrolyte, in particular to a production method of manganese sulfate electrolyte. Background technique [0002] Natural manganese ore with industrial application value mainly includes manganese oxide ore and manganese carbonate ore. According to the different grades and impurity content of manganese ore, there are currently two domestic and international methods for deep processing: one is for harmful impurities (such as phosphorus , sulfur) low-rich ores can be directly produced by pyrometallurgical technology to produce manganese alloy products or used as battery manganese powder; second, for most manganese carbonate and some manganese oxide ores, hydrometallurgical technology is generally used to produce a series of manganese salts product. However, with the mining of manganese ore resources year by year, the high-grade, low-impurity high-quality manganese ore is increasingly depleted....
