Embodiment Construction

[0036] Below in conjunction with specific embodiment and accompanying drawing, the present invention will be further described:

[0037] The process of comprehensive utilization of electrolytic manganese slag completes the following steps:

[0038] a. Mix electrolytic manganese slag and clear water in a beater at a ratio of 1:1.2 and beat into a slurry; take 500 kg of manganese slag and 600 kg of clear water.

[0039] b. Put the manganese slag slurry into the stirring tank and stir for 2 hours;

[0040] c. Filtrate and stir the manganese slag slurry;

[0041] D, 550 kilograms of filtrates obtained in step c and 500 kilograms of electrolytic manganese slags without washing are mixed in a beater and beaten into slurry;

[0042] E, the manganese slag slurry obtained in the step d is put into a stirring tank and stirred for 2 hours;

[0043] F, filter the manganese slag slurry after step e stirs, obtain the filtrate that manganese ion reaches about 13 grams / liter;

[0044] g. ...

Abstract

The invention relates to an electrolytic manganese slag processing method, in particular to an electrolytic manganese slag comprehensive utilization process. The method recovers the recyclable materials in electrolytic manganese slag through repeated water washing and filtering. The method can solve the air pollution source, particularly eliminate the water pollution source, and protect people health from being damaged. The method can extract higher-value chemical products through the scientific flow, and make the residuary filter residue into building products, thereby effectively utilizing the resource. Zero discharge is realized during the overall process of the technical proposal of the method, and because no additional chemical substances are added, additional environmental pollutioncan not be caused.

Description

technical field [0001] The invention relates to a treatment method for electrolytic manganese slag, in particular to a process for comprehensive utilization of electrolytic manganese slag. Background technique [0002] In the process of producing metal manganese, the electrolytic manganese plant will discharge a large amount of solid waste - manganese slag. Manganese slag not only occupies a large amount of land and devours good fields, but also the harmful gas emitted by manganese slag directly affects the health of nearby people, which is even more serious The most important thing is: the liquid seeping from the manganese slag slowly soaks into the ground to pollute the water quality, and the harmful substances include a variety of heavy metals and excessive ammonia nitrogen. At the same time, there is a considerable amount of available manganese, nickel, nitrogen, etc. in the electrolytic manganese slag. The current treatment methods of electrolytic manganese slag are di...
