[0002] The raw material for producing silicon is silica sand, which can be extracted from silica stone. The higher the purity of quartz sand, the easier it is to prepare high-purity silicon. Generally, low-purity quartz sand can be directly obtained from nature and can be used in the construction industry after being slightly broken. If high-purity quartz sand is needed, the iron impurities on the surface of the quartz sand and in the cracks need to be removed. Quartz sand is insoluble in acid and slightly soluble in potassium hydroxide solution. By utilizing this property, the quartz sand can be treated and purified by pickling. Currently, in China, quartz sand is pickled by using one or more of hydrochloric acid, sulfuric acid, oxalic acid, or hydrofluoric acid to dissolve iron impurities and the like.
