Abstract—The chemical and mineral compositions of the Kanash clay and sands from the Chuvash deposit are studied. The results of search for the decomposition of the Kanash clays by sulfuric and hydrochloric acids are presented for the further use of the prepared solutions as coagulants for the purification of drinking and waste waters. The preliminarily calcined clay is subjected to leaching and sulfating roasting followed by water leaching.
