Overview of the mechanism of action of sulfide ore collector
Mechanism xanthate and sulfide ore, before the 1950s proposed the so-called "chemical hypothesis" and "absorption hypothesis."
According to the chemical hypothesis: "The chemical reaction between xanthate and sulfide mineral surface, the smaller the solubility product of the reaction product, the more likely the reaction occurs."
The adsorption hypothesis believes that: mainly adsorption, which is divided into two factions, one is considered to be "ion exchange adsorption", that is, xanthogen ion and ion exchange on the surface of the mineral ion exchange adsorption; another group is considered "molecular adsorption", that is, yellow The ortho acid molecule or "ion pair" is adsorbed on the surface of the mineral.
In the 1950s , the importance of oxygen and oxidation was known. Later, a large number of interfacial electrical properties and electrochemical studies of flotation solutions were carried out. Therefore, the mechanism of action of xanthate has been well understood.
