ABSTRACT:
Disclosed is a method of increasing the silica to metal oxide ratio in alkali metal silicate solutions by removing smaller size anions from the solution using a strong cation exchange resin comprising: condensing the smaller size anions as silica in the pores of the strong cation exchange resin; leaving the larger, more siliceous anions in the external solution.
