An efficient method combining thermal annealing and acid

rapid thermal processing (RTP), silica is subjected to an acid leaching using an acid mixture solution (AS2) composed of HF (5%):HCl (4%) with a volume fraction of 1:7. During this acid leaching, which was carried out under power ultrasound, an excess of the obtained silica was abundantly dissolved in 10 ml of (AS2) solution for 4 h.

synthesis How to acid-wash sand? Chemistry Stack Exchange

In short, acid washing (or leaching) is supposed to remove impurities (mostly iron impurities) from the sand. From the introduction of the paper: Iron is one of the most troublesome impurities in silica sand because it impairs the transparency of high-quality glass, e.g. for tableware, and optical glass; it impairs transmission in optical

Five efficient methods of removing iron from silica sand

Oct 13, 2019· Iron removal by acid leaching separation is based on the fact that quartz is insoluble in acid (except H, impurity minerals containing Fe can be dissolved by acid solution), so that the purpose of removing iron-bearing minerals from quartz sand can be achieved. The acid leaching method can not only remove iron-bearing minerals from quartz sand, but also remove non-metallic impurity minerals

GB2192388A Process for leaching silica sand to reduce

A process for leaching silica sand to reduce the iron content thereof comprises the steps of drying- preheating the sand; vigorously mixing the preheated sand in a suitable intensive mixer, e.g. a rotating pan mixer, with sufficient sulphuric acid (e.g. 7.5 kg 100% H2SO4/tonne sand) to keep the surface of each grain of sand coated with a thin film of sulphuric acid during mixing; and retaining
