Technical field

The invention belongs to metal manganese waste slags to be in technical field, and in particular to a kind of Electrolytic Manganese Metal Residues are roasted through fluidized bed furnace Burn desulfurization acid preparation method.

Background technique

Manganese is strategic resource irreplaceable in national economy, and one ton of electrolytic manganese metal of every production can produce 5-10 tons Waste residue, the existing country's annual yield of Electrolytic Manganese Metal Residues is about more than 1,000 ten thousand tons, and sulfur-bearing is about the left side 8-10% in waste residue The waste residue on the right side, existing bulk deposition causes largely to endanger to ecological environment, in order to turn waste into wealth, efficiently uses having in waste residue Beneficial element is those skilled in the art of the present technique's technical issues that need to address.

Summary of the invention

The object of the present invention is to provide a kind of Electrolytic Manganese Metal Residues through boiling roaster desulfurization acid preparation method.

The technical solution for realizing the object of the invention is a kind of Electrolytic Manganese Metal Residues through boiling roaster desulfurization acid preparation method, The following steps are included:

(embodiment 1)

Fig. 1 shows a kind of specific embodiment of the invention, and wherein Fig. 1 is flow diagram of the invention.

See Fig. 1, a kind of Electrolytic Manganese Metal Residues are through boiling roaster desulfurization acid preparation method, comprising the following steps:

Step A, electrolytic manganese waste residue, iron concentrate and useless sulfur residue are mixed in a certain ratio and are put into feed bin；

Step B, by the material in feed bin by the way that it is de- to carry out roasting in certain temperature range in Belt Conveying to fluidized bed furnace Sulphur；

Step C, the waste material of step B is sent into dust removal slag in waste heat boiler；

Step D, the material in step C is sent into dust collecting system and is dusted operation, and the dirt slag of generation is excluded；

Step E, the material in step D is sent into purification system and is purified, obtained diluted acid and recycle selenium, surplus material It is sent into dry absorption tower；
