Electrolytic manganese slag comprehensive utilization technique

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 pollution can not be caused.

Description

A process for comprehensive utilization of electrolytic manganese slag technical field 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 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 curren...
