Abstract

Provided are methods of extracting silica and optionally lignin from an organic material, which includes adding a first acid to a liquids fraction separated from the organic material after treatment thereof with an alkali so as to facilitate at least partial precipitation of silica therefrom and then separating precipitated silica from the liquids fraction. The methods provided herein may optionally include adding a second acid to the liquids fraction so as to facilitate at least partial precipitation of lignin therefrom. In one form, the method further includes contacting the aforementioned liquids fraction with an ion-exchanger so as to facilitate at least partial substitution of a first cation of the liquids fraction with a second cation of the ion-exchanger, such that the liquids fraction is then suitable as a liquid fertilizer. Silica and lignin precipitates and a liquid fertilizer produced by the present methods are also provided.
