To clarify the dissolution behavior of K-containing silicate fertilizers produced by high-temperature sintering under acidic condition, the chemical element release and mineral evolution were investigated at ambient temperature in the extractants of hydrochloric and citric acids based on the chemical reactions of minerals contained in silicate fertilizer with acids. The results show that the more elements are released at a lower pH value of extractant. 2% citric acid with pH 2.1 is significantly more effective in dissolving the silicate fertilizer than hydrochloric acid with the same pH value. The dissolution rate of silicate fertilizer in hydrochloric acid at pH value of 0.3 is maximum, and only a mineral detected in the filter residue is leucite. Kaolinite and gibbsite are formed in the reactions of kalsilite and gehlenite with acid. Aluminum release is due to the further reactions of kaolinite and gibbsite with acid.
