May 16, 2018 Silica sand, also known as quartz sand, is mainly composed of silica( SiO2), which is the main raw material for making glass.Silica sand has ordinary silica sand, refined silica sand and high purity silica sand. The content of silica in ordinary silica sand is between 90 and 99 , the content of iron oxide is less than 0.02 , the content of silica in refined silica sand is between 99.Jan 27, 2011 Thus, we have studied etching effect on particle granulometric size during a primary step of leaching process on Algerian silica sand with HF at 20 during 2, 4 and 6 hours. Therefore, a new granulometric classification of the sand is noted. Particles with proportional high size are the latest influenced and the mass loss is increased with time of leaching.
Our work consists of the study of etching behavior of silica with HF, since this acid can significantly etch silica sand and change its particles size. Thus, we have studied etching effect on particle granulometric size during a primary step of leaching process on Algerian silica sand with HF at 20 during 2, 4.Silica sand washing process. Washed and graded. The grade of SiO2 in quartz sand decreases with the finer grain size of quartz sand, and the grade of impurity minerals is the opposite. This phenomenon is especially obvious in quartz sand containing a large number of clay minerals. Therefore, the quartz sand ore before the selection is carried out.
