PROCESSING OF SERPENTINITE TAILINGS TO PURE AMORPHOUS
Afteric separation, the nonic part of raw serpentinite was treated in 10 M hydrochloric acid to obtain a solid residue referred to as undissolved residue I as a source of silica. This residue was then washed in water until the pH value reached neutrality. Methods Preparation of the sodium metasilicate solution Sodium metasilicate solution SiO 2 : Na 2 O molar ratio = 1:1 was
