Problems solved by technology

[0003] Prior art CN2008103002906 proposes a process for producing manganese chloride tetrahydrate by absorbing chlorine-containing waste gas from low-grade rhodochrosite. The low-grade rhodochrosite powder is mixed with water to make slurry, which is then absorbed and reacted with chlorine-containing waste gas to obtain MnCl-containing 2 4H 2 O pulp, filter the pulp, add manganese sulfate powder and metal manganese powder to the filtrate to purify, filter, and evaporate the filtrate to obtain solid MnCl 2 4H 2 O product, this method obtains finished product purity low, contains many impurities, obtains single product, can not obtain the manganese chloride of various forms, is not suitable for industrial production manganese chloride

Embodiment approach 1

[0030] A manganese chloride production process, comprising the following steps,

[0031] S1, beating, put manganese carbonate or tide manganese carbonate into a beating machine for beating treatment, before beating, inject recycled water or tap water into the beating machine, after beating fully, obtain beating liquid A;

[0032] S2, water washing, stir the beating liquid A evenly and pump it into the washing tank, then add an appropriate amount of water, stir for 1 hour, stop stirring, settle for 3 hours, pump the upper layer of water, filter it through the plate frame, and then go to the sewage neutralization pool , the material suspended in the water recovered by the plate frame is reused, and a small amount of water and materials left in the washing tank are stirred evenly, and then pumped into the suction filter tank to obtain the washing liquid B;

[0033] S3, suction filtration, using a water ring vacuum pump to drain the water in the suction filtration tank, the mangan...

Abstract

The invention provides improvement of a technology for industrialized production of manganese chloride tetrahydrate and anhydrous manganese chloride, aiming at the problems of a production technologyof manganese chloride in the prior art that a product has more impurities and the form of the obtained product is single, and the production technology is not suitable for the industrialized production.

Description

technical field [0001] The invention relates to an improvement of a manganese chloride production process. Background technique [0002] The existing forms of manganese chloride include at least manganous chloride and manganese chloride tetrahydrate. The appearance of hydrated manganese chloride is rose-colored monoclinic crystal; the appearance of anhydrous manganese chloride is pink crystal. It is mainly used in the synthesis of medicines and the manufacture of feed additives, analytical reagents, dyes and pigments; the smelting of magnesium alloys and aluminum alloys, the production of brown and black bricks and tiles, and the manufacture of pharmaceuticals and dry batteries; it can also be used as a trace element fertilizer in agriculture. Manganese chloride can be divided according to whether it contains crystal water: anhydrous manganese chloride and manganese chloride tetrahydrate, and according to the number of crystal water: manganese chloride monohydrate, manganes...
