Silica Sand Etching Behavior During Leaching Process Using ...

30/09/2017  The aim of this study is to show how the design of experiments method (DOE) could be used as a practical method to model silica sand etching behavior during the leaching process. In the present work we have studied the etching effect on the particle granulometric size during a primary step of the leaching process on Algerian silica sand with hydrofluoric acid (HF) at 20% and 30% during 4

27/01/2011  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.

Extraction of Silica from Bengkulu Beach Sand using Alkali ...

extraction (leaching) method was used in three main steps. Bengkulu beach sand as precursors reacted with NaOH (alkaline fusion) at 95°C to form Na 2 SiO 3, then addition of HCl to form Si(OH) 4, and drying the silica gel becomes SiO 2. Based on the initial content analysis in Bengkulu sand contained 69.87% silica and other compounds with a lower percentage. The extracted silica was ...
