The mineral solubilization was studied in the concentration of solubilized Si and Al. The chemical leaching of the silicates was carried out using inorganic and organic acids as well as sodium hydroxide. The process was more effective in the alkine than in the acid pH range. In the acid medium, oxalic acid showed maximum acidity and a tendency to form complex structures, especially with aluminium, and was most effective in leaching.<\/jats:p><jats:p>The microbiological influence on solubilization reactions was tested using a number of microorganisms among them acid, alkali and slime\u2010forming species.
