What flotation reagents are included in the ore dressing wastewater, and how to deal with it?

The ore dressing wastewater has the characteristics of large water volume, high suspended solid content and many types of harmful substances. Its harmful substances are heavy metal ions and mineral processing chemicals. Heavy metal ions include copper, zinc, lead, nickel, antimony, cadmium, and arsenic and rare elements.

The flotation reagents added during the beneficiation process are as follows:

(1) Collecting agents: such as xanthate (RocssMe), black medicine [(RO) 2PSSMe], white medicine [CS (NHC6H5) 2]; (2) inhibition: such as cyanide salt (KCN, NaCN), water glass ( Na2SiO3); (3) Foaming agent: such as turpentine, cresol (C6H4CH30H); (4) active punishment: such as copper sulfate (CuS04), heavy metal salts; (5) vulcanizing agent: such as sodium sulfide; (6) ore Paddle conditioner: such as sulfuric acid, lime, etc.

The ore dressing wastewater can effectively remove suspended solids from the wastewater through the tailings dam, and the content of heavy metals and flotation reagents can also be reduced. If the emission requirements are not met, further treatment should be carried out. The common treatment methods are: (1) lime neutralization and roast dolomite adsorption can be used to remove heavy metals; (2) ore flotation can be used for main flotation reagents. , activated carbon adsorption method; (3) cyanide-containing wastewater can be chemical oxidation.
