Us4401638a Process For Purifying Silica Sand Google. A process of purifying silica sand comprises grinding sandstone, washing and desliming the ground sandstone to remove the major part of the clay-type binder, attrition-scrubbing the deslimed sand particles to release further amounts of binder therefrom, washing and desliming to remove said binder, drying and heating the sand particles.
The second stage feed stock of a beach sand mineral processing plant and finally a „fine sand‟ of below 180 m which after milling can be use for investment casting. Thus almost all the fractions can be made use of. [Key words Silica sand Beneficiation XRD Magnetic separation.] Introduction.
