Abstract

Process for obtaining alumina from alunite, characterized in that the alunite is roasted and activated in the oven at a temperature between 500 and 900ºC to proceed, after a fine grinding, to treat it with sulfuric acid for a short period of time and at a temperature of boiling, then making the separation of sterile and leaving a liquid from which, by cooling, potassium alum and ammonium are obtained, which are purified by crystallization and washing.
