Description
Technical field
The present invention relates to the desulfurization technology of Ferromanganese Ore, and in particular to a kind of sulfur method of Ferromanganese Ore.
Background technology
Ferromanganese Ore is important raw mineral materials, is mainly used in part in metallurgy industry, particularly smelting iron and steel, but Ferromanganese Ore
Material can be adversely affected to smelting, such as, sulfur content is larger to smelting fluctuation, and solubility of the sulphur in iron is minimum, part
It is present in steel with the form of FeS, on the one hand, so that steel brittleness increases, on the other hand, FeS and Fe can form low melting point (985
DEG C) eutectic, be distributed on the crystal boundary of austenite, when steel be heated to about 1200 DEG C carry out thermal pressure process when, on crystal boundary
Eutectic has been dissolved, and intercrystalline is combined and is destroyed, and then makes steel in process along grain boundary separation, so, it is to ensure smelting
The quality of refining, it is necessary to carry out desulfurization process in advance to Ferromanganese Ore.
In the prior art, general to use sintering process desulfurization, technique is skillful, but heat consumption is big, high cost, and the sulphur for removing
Air is entered with gas form, air pollution is caused；Patent No. 201310242967.6《It is a kind of to high-sulfur manganese spar》It is public
A kind of desulfurizing agent that utilization vanadic anhydride and 2.6- anthraquinones disulfonic acid or vanadic anhydride and tannin extract cooperatively form has been opened to water chestnut
Manganese ore carries out desulfurization process, and the method desulfurized effect is good, and energy consumption is smaller, but the time is long, and reagent dosage is big, and this law is based on water chestnut manganese
Ore deposit self component is simple, mainly belongs to trigonal system containing manganese, iron, calcium, zinc, and crystal, therefore desulfurization process are easier to；And Ferromanganese Ore
The harmful substance contents such as complicated component, lead, silver, cadmium, arsenic are high, and crystal belongs to tetragonal crystal system, thus Ferromanganese Ore desulfurization process difficulty compared with
Greatly, therefore, the sulfur method of Ferromanganese Ore still needs to numerous studies.
Therefore, the present inventor studies Ferromanganese Ore and desulfurization technology for many years, for the sulfur method of Ferromanganese Ore provides a new think of
Road.
The content of the invention
The present invention in order to solve the above technical problems, provide a kind of pollution-free, consumption less, the good Ferromanganese Ore of low cost, effect
Sulfur method.
It is achieved especially by following scheme：
A kind of sulfur method of Ferromanganese Ore, comprises the following steps：
(1) Ferromanganese Ore is crushed to granularity for 150-200 mesh, sieving obtains miberal powder；
(2) under the conditions of 80-120 DEG C, to adding water to stir in miberal powder, slurry is obtained；
(3) slurry is stirred, while being filled with sulfur dioxide gas, after stirring 30-40min, after standing 10-20min, addition is helped
30s is stirred in agent, wherein, promoter addition is the 1/30-1/20 of slurry volume, obtains intermediate material；
(4) by cellulose addition intermediate material, after stirring 20-50min, separate, obtain flock, solid and sulfate
Solution.
Amount of water is 2-3 times of miberal powder weight in the step (2).
Mixing speed is 60-120r/min in the step (3).
Sulfur dioxide gas are added in the step (3), its addition is the 1/10-1/5 of slurry volume.
It is 1 that auxiliary agent presses peracetic acid, sodium bismuthate, the mass ratio of Na2Fe04 in the step (3):1-3:2-5 is mixed.
Mixing speed in the step (3) and (4) is 30-60r/min.
The addition of cellulose is the 1/70-1/50 of slurry volume in the step (4).
Beneficial effects of the present invention
The present invention combines stirring by being filled with sulfur dioxide gas in slurry so that slurry sulfur dioxide absorption and
In acidity, further, the auxiliary agent prepared is added, with reference to rational raw material proportioning so that the low price sulphur in miberal powder is oxidized to high price
The soluble sulphur of state, adds cellulose so that heavy metal ion in intermediate material occurs complex reaction with it, also, by
In S2-Electronics ground state is first transitted to by excitation state, then transit to excitation state, wherein, given off energy when transitting to ground state, this
Energy just supplies the energy absorbed needed for chemical bond rupture, when there is complex reaction in heavy metal and cellulose, be bonded to and
Give off energy, this portion of energy supplies energy needed for electron transition to excitation state again；By laggard to ferrimanganic miberal powder before processing
Row manganese, sulphur content determination experiment, obtain, and desulfurization degree is up to 93%, and is less than 1.5% through the sulfur content of the Ferromanganese Ore after treatment,
Higher than 1.3-1.7 times of the desulfurization degree of sintering process；In summary：The present invention have good desulfurized effect, low cost, it is pollution-free,
Also can remove lead, every etc. part harmful ion.
