Is a xanthate flotation of gold-containing sulfide mineral collector agents most commonly used, its chemical composition is dithiophosphoric carbonate, formula ROCSSMe, wherein R is C n H 2N + 1 type hydrocarbon, Me is a metal sodium Or potassium. The structural formula of ethyl xanthate is: The flotation properties of xanthate are mainly: The decomposition of xanthate promotes the ability to capture. It is obvious that the production of xanthogen can be reduced only by increasing the concentration of OH- ions.

1. Xanthate can interact with various metal ions to form insoluble xanthogenate. The insoluble order is: Au + , Ag + , Hg + , Cu 2+ , Pb 2+ , Ni 2+ , Zn 2+ , Fe 3+ , Mn 2+ , xanthate have the ability to capture the sulfide or metal of these metals, and the activity of the capture is basically consistent with the poor solubility.
2. The ability of xanthate to collect significantly increases with the growth of non-polar hydrocarbon chains. This is mainly due to the difference in contact angles formed by different hydrocarbon chain lengths. The longer the hydrocarbon chain, the stronger the hydrophobicity and the greater the contact angle formed.
3. Xanthogenate is unstable in solution, first dissociated into xanthogen ion, xanthogen ion and water are hydrolyzed to form xanthogen, xanthogen is unstable, decomposed into carbon disulfide and alcohol, and its reaction The formula is:
4. Xanthate itself is a reducing agent that is oxidized to complex xanthogen when contacted with oxygen in the air or in a solution with a high ionic phase. The recovery ability of the complex conjugated acid to the sulfide ore is weaker than that of the yellow drug.
Xanthate is easily soluble in water and has a rapid effect on the mineral surface without blistering.
