How to harmlessly treat the precipitation after the treatment of arsenic-containing soot?

After precipitation treatment, arsenic exists in the form of calcium arsenate and Iron arsenate, which is a dry and hazardous solid waste. There are eight common methods used to treat hazardous solid wastes: chemical, biological and physical methods. Chemical treatment of solid wastes containing arsenic is costly and in some cases produces air pollution. Large amounts of inorganic solid wastes have fewer applications.

Treatment and recovery of arsenic-containing fumes

In nature, arsenic is usually enriched in copper, lead, zinc, nickel, cobalt, gold and silver in the form of toxic sand (FeAsS), toxic sand (FeAsS2), toxic sand (FeAs2), Cu3AsS3, andrographite (As2S3) and dioecious (As2S3) minerals. During non-ferrous metallurgy, many high arsenic solid materials are produced, such as roasting and smelting dust. These materials contain up to 5 - 50% arsenic and also contain significant amounts of valuable metals that are returned directly to the smelting process, causing arsenic to circulate and accumulate in the system and therefore should usually be treated separately for arsenic removal.

Arsenic treatment manufacturers: the advantages of arsenic-containing fume treatment methods explained

Arsenic treatment manufacturer: arsenic-containing soot treatment method uses a large amount of heat generated by antimony oxidation to maintain the necessary temperature of the reactor and the temperature of the antimony liquid in the furnace; because the concentration of metallic antimony on the surface of the melt is dominant, the nature of metallic antimony is more active than lead and bismuth, so that the antimony in the alloy liquid oxidizes into antimony trioxide and volatilizes into the soot, while lead and bismuth remain in the bottom lead of the reactor, realizing two uses in one furnace.

Arsenic treatment manufacturers: arsenic-containing soot technology treatment methods?

Arsenic treatment manufacturers: We have all seen that the soot generated by the non-ferrous metallurgical industry now mainly comes from the smelting, roasting or slag fumigation and recovery process of ores in the extraction of heavy metals such as copper, lead, zinc, cobalt and tin. Of course, in this, copper dust contains valuable metals such as copper, lead and zinc, and its chemical composition is complex. The following is the technical treatment method for arsenic-containing fume and dust?

Arsenic treatment manufacturers: What are the hazards of arsenic-containing fumes to us?

Arsenic treatment manufacturers: do you know what arsenic-containing soot is? What is its role all about? On these issues I believe most of my friends still do not understand it. But we do not dump too anxious, today's article is mainly for you to tell about the arsenic-containing soot to us what are the hazards of it? If you are also interested in this topic, then look down with the editor, I hope you can bring some better help in the selection of the time after seeing it.
