Hot Acid Leaching Of Silica Sand

Improvement of Impurities Removal from Silica Sand by

(>99.9999%), its cycle of production consists firstly of enriching the silica by acid leaching. In the present work, we have tried to enhance the extraction rate of impurities from Algerian silica sand by means of sequential leaching process using several solvents like HF, HCl, H2SO4, NaOH. The study of leaching effect is followed by DRX and Backscattered Electron images analysis. Efficiency

Process for purifying silica sand - Materias

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, treating the hot sand with sulfuric acid to convert the

Acid leaching of silica sand - Laboratory Testing

Rheomet is exactly right - acid leaching could open up all sorts of problems (water balance, acid balance, water treatment, disposal of metals in solution, etc., etc.). You need to look at the value of the final product vs. the cost of processing. Unless this is a very high value sand you probably can't justify the hydromet cost. Gravity separation or density separation could work if you know
