THE REMOVAL OF CLAY AND SILICA FROM WATER

THE REMOVAL OF CLAY AND SILICA FROM WATER1 By Otto M. Smith2 Silica is found in natural waters in two forms, the one insoluble and the other soluble. In the latter it is usually known as silicic acid and is reported as SÌO2 in the ordinary water analyses. In solution it occurs in a colloidal form or in combination with the basic elements.

Five efficient methods of removing iron from silica sand ...

2019-10-13  Iron removal by acid leaching separation is based on the fact that quartz is insoluble in acid (except H, impurity minerals containing Fe can be dissolved by acid solution), so that the purpose of removing iron-bearing minerals from quartz sand can be achieved. The acid leaching method can not only remove iron-bearing minerals from quartz sand, but also remove non-metallic impurity minerals ...
