Water glass is an inorganic colloid that is the most commonly used inhibitor in flotation operations. Waterglass have a good inhibition of silica, silicate minerals and aluminosilicate minerals (e.g., mica, feldspar, garnet, etc.), as inhibitors of gangue heavy use. The water glass is a water glass agglomerate which is melted by quartz sand and sodium carbonate, and the sintered block is dissolved in water to form a paste colloid. Its composition is complex, containing sodium metasilicate Na2SiO3, sodium orthosilicate Na2SiO4, sodium disilicate sodium Na2SiO5 and SiO2 rubber particles. It is usually expressed by Na2SiO3. Boiled water glass quartz and sodium carbonate, the water glass properties are different due to the different proportions of the application materials. The ratio of Na2O to SiO2 is usually used to represent the composition of water glass. The ratio of mNa2O·nSiO2 is n/m. The modulus, floating water glass, mold n / m = 2.0 ~ 3.0, the common water glass quality standard modulus is 2.2. Water with a small modulus is strong in alkalinity, and it is difficult to dissolve and has a strong inhibitory effect. The inhibition of water glass is mainly HSiO3- and H2SiO3, the silicic acid molecule H2SiO3 and the silicate acid HSiO3- have strong hydration, and are a kind of hydrophilic particles and ions, HSiO3- and H2SiO3. Silicate minerals have the same acid radicals and are easily adsorbed on the surface of quartz and silicate minerals to form a hydrophilic film, which increases the hydrophilicity of the mineral surface and inhibits it.
