Silica Sand Abstract
USA
A process of purifying silica sand comprises grinding sandstone, washing and desliming the ground sandstone to remove the major part of the claytype binder, attritionscrubbing the deslimed sand particles to release further amounts of binder therefrom, washing and desliming to remove said binder, drying and heating the sand particles, treating the hot sand with sulfuric acid to convert the ...
