The beneficiation agent is a sodium salt of cellulose carboxymethyl ether, which is an anionic cellulose ether, which is a white or milky white fibrous powder or granule, has a density of 0.5-0.7 g/cm 3 , is almost odorless, tasteless, and hygroscopic. It is easy to disperse in water to form a transparent colloidal solution, and is insoluble in an organic solvent such as ethanol. The pH of the 1% aqueous solution is 6.5-8.5. When the pH is >10 or <5, the="" viscosity="" of="" the="" gel="" is="" significantly="" lowered,="" and="" the="" performance="" is="" optimal="" at="" ph=""> For heat stability, the viscosity rises rapidly below 20 °C, and the temperature changes slowly at 45 °C. The long-term heating above 80 °C can denature the colloid and the viscosity and performance are significantly reduced. Soluble in water, the solution is transparent; it is very stable in alkaline solution, it is easy to be hydrolyzed when it is acid, and it will precipitate when the pH is 2-3, and it will precipitate when it encounters multi-valent metal salt.

Soluble in water, the solution is transparent; it is very stable in alkaline solution, it is easy to be hydrolyzed when it is acid, and precipitation will occur when the pH is 2-3, and precipitation will occur in the case of polyvalent metal salts.

This product has a flocculation effect on the gangue and can control the influence of the slime. The inhibitory effect on pyroxene and hornblende is better than that of water glass, and it also inhibits magnesium-containing silicate.
