Description
Technical field
The present invention relates to the preparation of manganese sulfate electrolyte, specifically a kind of production method of manganese sulfate electrolyte.
Background technology
Mainly include manganese oxide ore and manganese carbonate ore with industrial application value in natural manganese ore, according to the taste of manganese ore
It is internal and international at present that deep processing processing typically is carried out to it using two kinds of processes with the difference of impurity content：When pair
In objectionable impurities（Such as phosphorus, sulphur）Low high-grade ore can be directly using pyrometallurgical smelting process production Mn series alloy product or as battery
Manganese powder；Second, for most of manganese carbonate and partial oxidation manganese ore, the general serial salt using hydrometallurgical technology production manganese
Product.However, with the exploitation year by year to manganese resource, GOOD TASTE, the ANOMALY IN FINE QUALITY MANGANESE DEPOSITS increasingly depleted of low impurity, therefore, for
The research and development and utilization for the complicated manganese ore that manganese content is low, impurity content is high, which turn into, improves domestic manganese ore deep processing enterprise in the world
The key of the market competitiveness, also largely determine that can manganese ore processing industry sustainable development.Existing manganese sulfate electricity
It is longer to solve the process time of liquid, influences production efficiency.
The content of the invention

Property three sections of carbon purifications.
As can be known from the above technical solutions, manganese ore is passed through sulfating roasting by the present invention, can be without using sulphur in follow-up leach
Acid, while production cost is reduced, also mitigate the pollution to environment significantly；It is simultaneously inside and outside using driving stirring rod to rotate
Axle is filtered to solution, and on the one hand the leachate that add barium sulphide can be stirred, and makes its reaction generation precipitation；It is another
Aspect makes interior axle enter filtering to leachate by lifting outer shaft, is achieved that stirring, filtering without other auxiliary equipments, significantly
Improve production efficiency.
Embodiment
The present invention is described in detail below, illustrative examples of the invention and explanation are used for explaining the present invention herein, but
It is not as a limitation of the invention.
The production method of manganese sulfate electrolyte, it comprises the following steps：
First, pyrolusite and pyritic material are worn into be blended in roasting apparatus in proportion after powder respectively and are calcined.If
The miberal powder particle diameter worn into reduces greatly the contact area of two kinds of ore deposits very much and can not sufficiently mixed, if the miberal powder particle diameter worn into
It is too small and can be entrained by the flow of air and can not complete to be calcined；Usually, the particle diameter that pyrolusite and pyrite wear into powder be 150 mesh~
250 mesh.At 560 DEG C~620 DEG C, roasting time is 3~4 hours for sintering temperature control.
Then, Selectively leaching is carried out to the mixture after above-mentioned roasting, obtains manganese sulfate leachate；Leaching agent selects
Water.After raw material high-temperature roasting, higher temperature is still kept when clinker is come out of the stove, higher temperatures can be reached by being directly added into clear water
Degree carries out leaching ore deposit, although then temperature declines, manganese substantially completely leaches within a short period of time, so not needing additional steam
Improve leaching ore deposit speed.The mass ratio of its reclaimed water and mixture is（5~7）:1, extraction time is 3~4 hours.After the completion of leaching,
Full elemental analysis are carried out to leachate, leachate is the manganese sulfate leachate containing impurity, the leaching rate more than 85% of manganese.
Then, manganese sulfate leachate is inputted to container, adds barium sulphide, 8g is added in about every liter manganese sulfate leachate
Barium sulphide, ensure the generation of precipitation.Then, start the stirring rod being arranged on outer shaft to be stirred, outer shaft is driven by motor to be revolved
Turn, realize automation stirring, stir while precipitating solution；After stir about 45min, outer shaft is lifted up, makes to be arranged on
Hollow interior axle in outer shaft is exposed close to one section of the container bottom；In implementation process, the interior axle bottom exposed be provided with
The opening of its inner chamber connection, opening is upper covered with filter screen, and the solution in container filters precipitation through filter screen, and the filtrate after filtering from
Flow out interior axle inner chamber.
In implementation process, interior axle passes through container bottom, and can be arranged on bottom by bearing, and outer shaft is then not passed through container
Bottom, inside and outside axle can be connected by flat key etc., so as to rotate simultaneously；When outer shaft drives stirring rod rotation, outer shaft blocks interior
The opening of axle, prevent solution from being flowed out from opening.After outer shaft stops the rotation, outer shaft is lifted up, exposes opening；Now solution can be from
The filter screen of opening flows into interior axle and obtains inner chamber, realizes filtering.In order to prevent precipitation from blocking filter screen, in filter process, interior axle can be made
Rotation, precipitation is thrown away to interior axle outside using centrifugal force, avoid precipitation from being gathered near filter screen.
Filtrate after filtering is flowed out from interior axle inner chamber, and three sections of purifications are carried out to filtrate, is electrolysed, obtains after leaching supernatant
Manganese sulfate electrolyte.Three sections of purifications purify to add one section of Sodium Dimethyldithiocarbamate, added two sections of purifications of potassium permanganate, add activated carbon
Three sections purification.Specifically, the amount for adding Sodium Dimethyldithiocarbamate is every liter of solution 0.6g, Sodium Dimethyldithiocarbamate heavy metal ion such as nickel and cobalt
With good impurity-eliminating effect, the concentration of iron ion is possible to or is unable to reach standard in one section of purification process, this process
Hydrogen peroxide should be also suitably added, the amount for adding hydrogen peroxide is every liter of solution 1ml；Then two sections of purifications are carried out, add potassium permanganate
Amount be every liter of 8g, while a small amount of sulfuric acid is added dropwise, makes pH=5, further arsenic in solution is cleaned；Finally carry out three sections only
Change, the dosage for adding activated carbon is every liter of solution 0.1g, and mixing time is 1 hour.Due to being gone back in the solution after two sections staticize
In the presence of a small amount of ferric ion, aluminium ion and silicon, it can form colloid, add activated carbon can aggregated colloids reach precipitation, mistake
Being stood after filter takes supernatant to be electrolysed, and qualified manganese sulfate electrolyte is made.
Above-mentioned embodiment is used for illustrative purposes only, and is not limitation of the present invention, relevant technical field
Those of ordinary skill, can be so that various changes can be made and modification without departing from the spirit and scope of the present invention, therefore institute
There is equivalent technical scheme also to belong to scope of the invention.
