Study of Filtration and Washing of Residue After HCL

Abstract. One of the process stages of kaolin clay processing to alumina is solid-liquid separation process after HCl leaching with subsequent washing of silica residue. Our laboratory studies have shown that of existing equipment most efficiently for this task pressure filter can be used.The major constituents of sand are silica and silicates. The facile and low-cost purification technology of silica from natural sand is of magnificent importance to the industrial applications of silicon-based materials. Herein, we report a green, low-cost, and universal method to purify silica from natural sand. Sand from deserts, rivers, and seas is selected A facile and universal method to purify silica from natural sand
