Water glass is an inorganic colloid, which is a regulator of flotation non-sulfurized ore or some sulfide ore. It has a good inhibitory effect on gangue minerals such as quartz and silicate. When using fatty acids as collectors , flotation of fluorite , calcite and scheelite , water glass can be used as a selective inhibitor. When the amount of water glass is large, it also has an inhibitory effect on sulfide ore. At the same time, water glass is often used as a dispersing agent for flotation to improve the stickiness of foam and improve the grade of concentrate. It is especially useful for flotation of materials with more mud. However, if the water glass is too much, it will make concentrate. Filtration is difficult. Studies have shown that when the amount of water glass is the same, the higher the "modulus", the more significant the inhibition effect.
