Description
Technical field
The present invention relates to new environment-protective process technical fields, in particular to a kind of comprehensive reutilization to be electrolysed 0 manganese slag and manganese tail
The technique of mine.
Background technique
In electrolytic manganese production process, every production 1t electrolytic manganese metal need to consume 7-8t of manganese ore, generate electrolytic manganese residues
5—6t.Currently, only the electrolytic manganese waste residue whole nation has just hoarded about 20,000,000 t, such as it is using manganese content by electrolytic manganese residues
1%-3% calculates, and the promoter manganese for being dropped or flowing damage is about 20-60 ten thousand t.Technique of preparing if do not improved manganese ore is reinforced
The development and utilization of manganese tailing, with the increase of manganese tailing amount, the environment and ecological problem of initiation will be more and more.Tailing is hoarded
Mining area ecological environment is caused constantly to deteriorate.Large scale mining and utilization with mineral resources, mining area environment system are affected
And destruction, the ecological environment problem that a large amount of manganese tailings cause also get worse, be mainly manifested in: 1. harmful element is dirty in manganese tailing
Environment is contaminated, due to hoarding for a long time for waste residue, some harmful elements are permeated by soil layer, and into surface water and groundwater, it is difficult to be formed
Degradation and reluctant pollution sources, can make river biology disappear, and groundwater resources are scrapped, are detrimental to health；2. destruction area
Domain ecology, since mine soil lacks nutriment, and excessively high can generate to root system of plant of the content of beary metal such as manganese, iron is poisoned, and is extended
The natural vegetation restoration time on discarded ground, while causing biology to migrate and being obstructed, bio-diversity reduces；3. damage to land provides
Source, afield intermountain can not be handled a large amount of manganese tailing manganese slag muck products, not only take up agriculture plantation, also the geology calamity such as induction mud-rock flow
Evil；4. causing other social concerns, mine waste residue is hoarded, and is increased the expenses such as enterprise's land acquisition and place disposition and is increased production
Cost, and agriculture plantation is largely occupied, intensify the contradiction between enterprise and resident.
While the ecological environment ability evaluation and analysis of manganese ore industry development promotes rapid economic development using promoter manganese, demanganization money
Outside relationship between source utilization efficiency and industrial benefit, there is also Resources Reserves to the stress Game Relationship of environment.And in ecology
While environmental quality index gradually decreases, manganese ore industrial harmonization degree is gradually increased, and illustrates the development of Guangxi manganese mining industry to ecology
The dependence of environment is in be gradually reduced trend.It develops a circular economy, builds Ecological Park, carries out pollution-free industry, can gradually decrease
Destruction to ecological environment.
Titanium white production enterprise uses Titanium White Production By Sulfuric Acid Process, and Titanium White Production By Sulfuric Acid Process can generate a large amount of titanium white
Spent acid.If dealt with improperly, these titanium white waste acids can cause local environment seriously to pollute.Currently, the processing side of titanium white waste acid
Formula is roughly divided into two kinds, and first way is in spent acid and quick lime and will to generate calcium sulfate precipitation, then puts neutralization slag muck
To cinder field；The second way is to be concentrated in vacuo spent acid by steam heating, and acid-spending strength is improved to after 70%, then with
98% concentrated sulfuric acid carries out complex acid, returns to titanium dioxide acid hydrolysis workshop section and uses.The first processing mode can generate a large amount of sulfate slag, due to
Impurity content is more, non-recovery utility value, these waste residues can only discard stockpiling, and occupy a large amount of land resource.Second
Kind of processing mode then complex process, cost recovery is high, therefore not all titanium white production enterprise all has ready conditions application.Cause
This, each titanium white production enterprise needs to find more economical reasonable titanium white waste acid recovery and treatment method, can become give up into
Treasured realizes the utilization again of resource.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide the technique of a kind of comprehensive reutilization electrolytic manganese residues and manganese tailing
The problem of being proposed in background technique.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of comprehensive reutilization electrolytic manganese residues and
The technique of manganese tailing, specifically includes the following steps:
