Abstract
The present invention relates to a kind of purification method of electrolytic manganese metal, and it, which is used, inputs manganese sulfate leachate to container, adds barium sulphide, starts the stirring rod being arranged on outer shaft and is stirred, precipitates solution；Outer shaft is lifted up, make to be arranged on hollow interior axle in outer shaft close to the container bottom one section exposes；One section interior axle of the solution through exposing in container filters out precipitation；Filtrate after filtering is flowed out from interior axle inner chamber, and the filtrate of outflow enters the purification being arranged on the downside of container and purified.The present invention is filtered using the inside and outside axle for driving stirring rod to rotate to solution, and on the one hand the leachate that add barium sulphide can be stirred, and makes its reaction generation precipitation；On the other hand interior axle is entered filtering to leachate by lifting outer shaft, so as to which precipitation is retained in container, is achieved that stirring, filtering without other auxiliary equipments, substantially increases production efficiency.
Description
Technical field
The present invention relates to a kind of purification method of electrolytic manganese metal.
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.Electricity is prepared existing
During solving manganese metal, impurity and purification need to be carried out to middle the product sulfur acid manganese solution, and current manganese sulfate electrolyte is net
Change time length, influence production efficiency.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of purification method for the electrolytic manganese metal for improving production efficiency.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of purification method of electrolytic manganese metal, its
Using the following steps：
（1）Manganese sulfate leachate is inputted to container, adds barium sulphide, starts the stirring rod being arranged on outer shaft and is stirred
Mix, precipitate solution；
（2）Outer shaft is lifted up, make to be arranged on hollow interior axle in outer shaft close to the container bottom one section exposes；
（3）One section interior axle of the solution through exposing in container filters out precipitation；
（4）Filtrate after filtering is flowed out from interior axle inner chamber；
（5）The filtrate of outflow enters the clarifier-tank being arranged on the downside of container；
（6）Sodium Dimethyldithiocarbamate is added in clarifier-tank to purify filtrate.
Preferably, 8g barium sulphides are added in every liter of manganese sulfate leachate.
Preferably, mixing time 45min.
Preferably, the interior axle bottom exposed is provided with the opening that connect with its inner chamber, be open on covered with filter screen.
Preferably, it is provided with stirring slurry in the clarifier-tank.
Preferably, the amount of Sodium Dimethyldithiocarbamate is every liter of solution 1g.
As can be known from the above technical solutions, the present invention is filtered using the inside and outside axle for driving stirring rod to rotate to solution, and one
Aspect can be stirred to the leachate for adding barium sulphide, make its reaction generation precipitation；On the other hand made by lifting outer shaft
Interior axle enters filtering to leachate, and so as to which precipitation is retained in container, stirring, mistake are achieved that without other auxiliary equipments
Filter, substantially increases 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.
A kind of purification method of electrolytic manganese metal, it uses the following steps：
First, manganese sulfate leachate is inputted to container, adds barium sulphide, 8g vulcanizations are added in about every liter manganese sulfate leachate
Barium, 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 rotated, real
Now automation stirring, is stirred while precipitating solution；
After stir about 45min, outer shaft is lifted up, makes to be arranged on the hollow interior axle in outer shaft close to one section of the container bottom
Expose；In implementation process, the interior axle bottom exposed is provided with opening connect with its inner chamber, be open on covered with filter screen, container
Interior solution filters precipitation through filter screen, and the filtrate after filtering is flowed out from 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.
Enter the clarifier-tank being arranged on the downside of container from the filtrate of interior axle outflow, Sodium Dimethyldithiocarbamate is added in clarifier-tank to filtrate
Purified.And the addition of Sodium Dimethyldithiocarbamate is every liter of solution 1g, and the stirring slurry that can be rotated with interior axle is provided with clarifier-tank, made
The solution obtained in clarifier-tank fully precipitates, and realizes the purpose of purification.In implementation process, Sodium Dimethyldithiocarbamate heavy metal ion such as nickel
There is good impurity-eliminating effect with cobalt, the concentration of iron ion is possible to or can not reach standard in purification process, this process
Hydrogen peroxide can be also suitably added and remove standard to reach iron ion.
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.
