magnetic separator for gypsum

Chemical iron removal primarily employs inorganic acids for leaching, utilizing chemical reactions to eliminate iron oxide films on fine-grained ilmenite or quartz particles. This method works by reacting with iron impurities through inorganic acids, converting them into soluble substances that can then be removed via water washing and PTMS magnetic separation processes.

PTMS magnetic separation

In the chemical iron removal process, common inorganic acids include hydrochloric acid, sulfuric acid, and nitric acid. These highly corrosive acids react with iron impurities to form soluble iron salts. When hydrochloric acid reacts with iron oxide, it produces ferric chloride and water. The ferric chloride can dissolve in water, allowing its removal through the PTMS magnetic separation process.

what is magnetic separation used for？

In recent years, some new progress has been made in the field of chemical iron removal. The combination of thiourea dioxide and tetra-sodium diacetic acid glutamate is used to realize PTMS magnetic separation iron removal and whitening by reducing trivalent iron oxide into soluble divalent iron ions. This method has the advantages of environmental protection and low corrosiveness.
