FIELD: production of alumopotassium alum. SUBSTANCE: the crushed alunite ore is roosted, treated with a sulfuric acid solution and the solution is separated from a solid residue. Potassium chloride is added to the solution in a stoichiometric ratio to the amount of sodium ions and the solution is cooled. EFFECT: greater efficiency of the process.
