Manganese slurry is heated to 90~130 degrees Celsius by S4, and the benzoquinone after collecting vaporization, temperature is too low, and benzoquinone is not
It can vaporize completely, the excessively high benzoquinone of temperature will appear coking phenomenon, both will affect the rate of recovery of benzoquinone, using this
The rate of recovery of method benzoquinone is up to 97% or more；
S5, by manganese slurry be cooled to 55 degrees Celsius or less (temperature is excessively high, in ammonium hydroxide with when ammonium hydroxide volatilization loss it is larger),
Ammonium hydroxide is added in manganese slurry, the pH value that manganese is starched is adjusted to 5~7, and (under this pH condition, the impurity other than manganese is deposited in solid form
), by manganese slurry by filter press separating and filtering, obtain slicker solder slag (lead, tin the rate of recovery can achieve 99% or more) and sulfuric acid
Manganese solution；
MeSO4+(NH4)2S→MeS+(NH4)2SO4, Me indicates the heavy metals such as lead in this chemical formula.
Manganese sulfate solution is controlled at 15~50 degrees Celsius, ammonium hydrogen carbonate is added in manganese sulfate solution, obtains carbonic acid by S6
Manganese and ammonium sulfate；
MnSO4+NH4HCO3→MnCO3+(NH)2SO4+CO2
S7, evaporation ammonium sulfate recycling ammonium sulfate do agricultural fertilizer, by manganese carbonate after deionized water is washed 830~
In 1000 celsius temperatures calcining obtain solid-state mangano-manganic oxide, by solid-state mangano-manganic oxide after crushing or frosted, spend from
Sub- water washing dries to obtain finished product mangano-manganic oxide.
MnCO3→Mn3O4+CO2
In a kind of method using aniline reduction electrolytic manganese anode mud production soft magnetism mangano-manganic oxide above-mentioned, the step
Rapid S5 further includes following methods：The manganese sulfate solution is collected, ammonium sulfide solution is added in manganese sulfate solution, removes manganese sulfate
Heavy metal in solution.MeSO4+(NH4)2S→MeS+(NH4)2SO4, Me indicates the heavy metals such as lead in this chemical formula.
In a kind of method using aniline reduction electrolytic manganese anode mud production soft magnetism mangano-manganic oxide above-mentioned, the step
Rapid S1 further includes following methods：Manganese anode slime particle is milled to -120 mesh hereinafter, then adding water slurrying.
In a kind of method using aniline reduction electrolytic manganese anode mud production soft magnetism mangano-manganic oxide above-mentioned, the manganese
The Manganese anode slime generated when the earth of positive pole is electrolytic manganese.
In a kind of method using aniline reduction electrolytic manganese anode mud production soft magnetism mangano-manganic oxide above-mentioned, by aniline
Be no more than in reaction kettle controlled at controlling value, aniline is added in manganese slurry.
Compared with prior art, lead, tin, the antimony etc. in the original earth of positive pole are remained after benzoquinone of the present invention, manganese are recovered, in slag
Element and a small amount of manganese, because the quantity of slag significantly tails off, therefore in slag, slicker solder antimony content significantly increases and by enriching and recovering.The technique is at one stroke
Three, manganese, benzoquinones are not only recycled, but also recycled the valuable elements such as the lead in the earth of positive pole to the greatest extent, while perfect
Solve the Manganese anode slime bring wasting of resources of electrolytic manganese manufacturer and problem of environmental pollution.
The present invention is further illustrated With reference to embodiment.
