The final quartz sand concentrate was obtained by leaching quartz sand after beneficiation at 70 °C with 3 mol/L hydrochloric acid + 1 mol/L acetic acid + 0.5 mol/L hydrofluoric acid in the first stage and 3 mol/L hydrochloric acid + 1.5 mol/L sulfuric acid in the second stage for 2 h. The SiO 2 content in the concentrate increased to 99.92%.
