    2011-1-27 · 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.Materials Science Improves Silica Sand Strength SPE,2014-2-26 · As formation closure stress increases, materials that can withstand stronger stresses than silica sand, such as resin-coated sands and ceramic proppants, must be used. Resin-coated silica proppant can be used up to about 8,000 psi closure stress, improving fracture treatment results; ceramics made of aluminosilicates ores are much stronger and
