Flotation with Sodium Silicate Acting as a Depressant is used to Recover Silicon from Metallurgical-Grade Silicon-Refined Slag

Dandan WU

A sodium silicate (SS) depressant-based flotation recovery method for silicon from metallurgical-grade siliconrefined slag (silicate) was proposed. The arrangement science, contact point, and zeta potential estimations were utilized to grasp the association instruments of SS on the silicate. With SS expansion, the substance of recuperated silicon expanded. During the buoyancy cycle, SS was hydrolyzed into firmly hydrophilic, which could be truly or artificially adsorbed with silicate. This adsorption permitted the contact point of the silicate surface to diminish from 6.62° to 0°, showing the diminishing agreeability of the silicate.
