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 …

It is found that the iron on the surface of silica sand and matrix of silica sand can be eliminated more efficiently by sonication than by mechanical scrubbing. Furthermore the iron elimination rate can be raised when the sonication combine with chemical process, such as the iron elimination use acid leaching process [5].

On the other hand, at temperatures as low as 10C the addition of 5 - 1 0 m g / L Fe 2 to the initial solution strongly accelerates the iron dissolution process. From the above phenomena it is deduced that thermodynamic and kinetic inhibitions are taking place during leaching of silica sand in oxalate solutions.
