Abstract
Procedeul pentru recuperarea din jarositul potasic, a SO3, a Fe2O3 si a K2SO4 ca atare sau convertit în Na2SO4 si KOH, conform inventiei, consta în aceea ca jarositul potasic, este supus descompunerii termice la temperatura de circa 1000 degree C, timp de 1h, rezultînd pe de o parte SO3 valorificabil sub forma de H2SO4 si pe de alta parte un amestec solid format din FeO3 si K2SO4 din care, în continuare prin spalare, uscare si macinare poate fi valorificat în industria pigmentilor sau pentru obtinereafierului moale si K2SO4 sub forma de solutie care prin concentrare si cristalizare poate fi valorificat ca atare sau solutie de K2SO4 poate fi trecuta peste o rasina schimbatoare de ioni medie bazica în forma OH, cînd are loc retinerea anionului SO4laputerea 2- si formarea în efluent a KOH care poate fi utilizat la obtinerea jarositului potasic, iar prin regenerarea rasinii cu o solutie de NaOH rezultînd o solutie de Na2SO4 care poate fi valorificat prin cristalizare.
