Description
Technical field
The invention belongs to manganese production technical field, especially a kind of pair of electrolytic manganese residues carry out the composition that processing is used.
Background technique
China is currently the first Chan Meng big country in the world, and manganese metal is used for steel and iron industry, there is saying for " no manganese not Cheng Gang ", manganese
It is one of the important basic supplies of Chinese national economy and national grand strategy resource, therefore the production of manganese is particularly significant.
The production technology of manganese mainly includes electrolysis method, aluminothermic process and electro silicothermic process, and the method for industrial production manganese is electrolysis method.
The production cost of electrolysis method is higher, and the purity for the manganese that can be generated a large amount of electrolytic manganese residues, but produce is good.
Electrolytic manganese residues are the pollution sources that electrolytic manganese industry is maximum, most dangerous, and it is a generation that Electrolytic Manganese Metal Residues, which recycle,
Criticality problem.China is the maximum electrolytic manganese metal production in the whole world, consumption and exported country, and production capacity is more than 2,000,000 tons, Zhan Quanqiu
The 98% of electrolytic manganese aggregated capacity.Electrolytic manganese residues are the filtering acid sludges generated after electrolytic manganese metal, are the emphasis pollutions of electrolytic manganese industry
Object.For electrolytic manganese residues yield up to 7 ~ 11 ton/ton manganese, annual yield is about 20,000,000 tons, is accumulated over 80,000,000 tons over the years, deposits
It measures huge.Currently, enterprise not yet finds the method for dealing carefully with electrolytic manganese residues, generally electrolytic manganese residues are transported to stockyard and are built a dam heap
It puts.Domestic electrolytic manganese residues tailing dam takes up a large area, and safety coefficient is low, and for a long time under the action of Weathering And Leaching Behavior, polluted big
Piece arable land and underground water source, do great damage to ecological environment.
There are mainly two types of for the conventional process mode of electrolytic manganese residues:
First is that electrolytic manganese residues sorting process technology.The technology utilizes the alternate different physicochemical characteristics of each mine of electrolytic manganese residues, will
Various composition separates, and the magnetic separation fine fodder such as obtained using the magnetism of manganese can become the acceptable material of production electrolytic manganese.
Second is that electrolytic manganese residues solidification technology.Inertia is fixed or be wrapped in harmful components in electrolytic manganese residues by the technology
Solidification basic material in, be a kind of method for innocent treatment.It is generally using cement as the basic material for solidifying addition, cement
Additive amount be no less than 45%.
In recent years, the grade of manganese ore gradually decreases.Meanwhile with the raising of production technology level, the effect of production link
Rate is continuously improved, and the content of manganese in electrolytic manganese residues further decreases, and the manganese in electrolytic manganese residues has been difficult through sorting process
Method recycles again.Although curing process effect is good, for being piled into the electrolytic manganese residues on mountain, this method may disappear
A large amount of cement is consumed, the increase of processing cost certainly will be will cause, industrial applications prospect is general.
A large amount of electrolytic manganese residues are hoarded, and bring very big pressure to Environmental Protection in China work.Recycling is carried out to electrolytic manganese residues
It utilizes, not only can solve its pollution problem to environment, additionally it is possible to create benefit for enterprise, reduce production cost.Currently, electric
The resource utilization of solution manganese slag is mainly the following mode:
One, valuable metal is recycled.Manganese in electrolytic manganese residues resource accounting reaches 9%~13%.The recovery method of manganese mainly have bioanalysis,
Acidic leaching method and three kinds of water washing and precipitating method.Bioanalysis mainly utilizes sulfur-oxidizing bacteria and iron-oxidizing bacterium to leach in electrolytic manganese residues
Manganese, the leaching rate of manganese is up to 90% or more.Acidic leaching rule adds acid leaching solution, leaching auxiliary agent in electrolytic manganese residues, surpasses
The higher manganese sulfate product of purity can be obtained after sound, removal of impurities.The method that water washing and precipitating method uses " clear water washery slag+ammonium salt precipitating "
Soluble manganese is recycled, the rate of recovery of manganese can reach 99% or more, and in the rich manganese precipitating material recycled, the content of manganese can reach 30%
More than.Acidic leaching method and water washing and precipitating method due to complex process, higher cost and will cause secondary pollution, cause using by
Limit.Bioanalysis is the method for the recycling manganese in electrolytic manganese residues and other metal ions of a great potential, but to strain and leaching
Condition it is more demanding, and the bioleaching time is generally longer.In addition, the cultivation of strain is also more complicated, still fail at present
Find most suitable strain.
Two, all-sided fertilizer is prepared.Rich in macronutrient required for organic substance and plant in electrolytic manganese residues, as manganese,
Selenium, potassium, sodium, iron, boron etc., this provides possibility to prepare all-sided fertilizer using electrolytic manganese residues.Currently, the full price of electrolytic manganese residues preparation
Though fertilizer can increase certain fertilizer efficiency, its fertilizer efficiency is not so good as common nitrogenous fertilizer and phosphate fertilizer.In addition, also containing many harmful members in electrolytic manganese residues
Element, promote crop growth while also can contaminated soil, endanger human health.If can be right before applying electrolytic manganese residues fertilizer
It carries out harmless treatment, then electrolytic manganese residues fertilizer will be widely adopted in agriculture actual production.
Three, materials for wall is produced.Electrolytic manganese residues mainly contain silica, calcium oxide, iron oxide and aluminium oxide etc., are suitble to
For brickmaking.Currently, having non-burning brick, fired brick, Ceramic Tiles, steam-pressing brisk and heat preservation using the major product that electrolytic manganese residues produce
Brick.Electrolytic manganese residues have in the main problem for preparing materials for wall: first is that the mixed ratio of electrolytic manganese residues is relatively fewer, increasing and add
Amount will lead to the intensity decline of brick body；Second is that heavy metal and poisonous impurities need to be removed further in electrolytic manganese residues.
Four, roadbed material is produced.Electrolytic manganese ground-slag is free of the asphalt of clinker with addition of flyash and carbide slurry preparation,
Stability, intensity, adhesion and the anti-corrosion property energy of asphalt can be effectively improved.The asphalt uses anti-after 1 year
Compressive Strength still can reach 10 megapascal, meet the requirement of traffic construction.It is prepared when the additive amount of electrolytic manganese residues reaches 80%
Asphalt mastic and asphalt performance and economy it is best.Certainly, electrolytic manganese residues are promoted on a large scale in highway subgrade
Application in terms of material must consider that " poisoning " of heavy metal ion in electrolytic manganese residues influences.Heavy metal in electrolytic manganese residues from
Son can be by the soil near rain penetration to roadbed, to influence its surrounding enviroment.
Currently, the application technology as the second resource research of electrolytic manganese residues is in theoretical research stage mostly, in actual industrial
What is be applied is very few, and reason mainly has following two points: first is that recycling electrolytic manganese residues in manganese metal can not obtain it is good
Good economic benefit, and secondary use value is little.Second is that electrolytic manganese residues in cement industry, materials for wall, prepare all-sided fertilizer etc.
During the resource utilization in field, it is required to consider the harmless treatment to harmful element or heavy metal, higher cost.
Application publication number is CN107649488A, and date of publication is on 2 2nd, 2018, applies for the China of artificial Tsinghua University
