grinding and purification silica

Enhancing the separation of silica nanoparticles from ...

2016-6-13  Magnetite was applied to the silica removal in backside grinding wastewater. • The best SiO 2 removal was achieved to be about 97%.. The optimum dosage of magnetite was determined as 16 mg/L.. The pH should be maintained at less than 10 to prevent deterioration of SiO 2 removal.. Mixing and sedimentation in magnetic field were also important parameters.
