Abstract

In this study, the enrichment possibilities of silica sands containing 82.03% SiO₂, 3.13% Al₂O₃, 0.48% Fe₂O₃, and 0.17% TiO₂ obtained from Cam-İş Madencilik A.Ş. (Bilecik) were investigated by physical and chemical methods. As a result of the magnetic separation enrichment tests, a silica concentrate in suitable chemical composition and usable quality could not be obtained. After the dispersion and classification process, the silica concentrate containing SiO₂ of 96.30% and Fe₂O₃ of 0.30% was obtained by using Na₂SiO₃ as depressant and Derna 7 as collector in the flotation process carried out at pH 9. Since impurities could not be removed sufficiently by flotation, oxalic acid leaching was applied. As a result of oxalic acid leaching carried out on the silica concentrate obtained with flotation, 97.18% SiO₂ and 0.054% Fe₂O₃ contents were reached in silica sand.
