Sodium Silicate

• Sodium Silicate (Na2SiO3) is also used as a modifier in froth flotation cells. It is added to the pulp to create a silica film on the surface of minerals such as quartz, feldspar, and mica. This film reduces the adsorption of collectors on the mineral surface and prevents the minerals from floating. Sodium Silicate is also used to disperse clay minerals, which can interfere with the flotation process.
