Jan 27 2011nbsp018332Thus we have studied etching effect on particle granulometric sie 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 sie are the latest influenced and the mass loss is increased with time of leaching.
