Description
Znanem jest otrzymywanie z surowego langbeinitu tak zwanej kalimagnezji, nato¬ miast wedlug wynalazku z langbeinitu wy¬ twarza sie siarczan potasu i siarczan ma¬ gnezu.Surowy langbeinit po zmieleniu uwalnia sie od chlorków przez przemycie zimna woda. Tak przemyty langbeinit, prawie wolny od chloru, rozpuszcza sie na goraco powyzej 90° w mieszaninie macierzystych lugów szenitowych i siarczanowych z do¬ datkiem wody. Otrzymany goracy roztwór langbeinitowy uwalnia sie od zawiesiny ilów, poczem studzi do temperatury okolo 25°, przyczem wypada z roztworu szenit.Oddzielone od lugu krysztaly szenitu mie¬ sza sie z woda w temperaturze okolo 55°, przyczem wypada siarczan potasu. Otrzy¬ many siarczan potasu, w postaci drobnych krysztalów, oddziela sie od lugu macierzy¬ stego na goraco. Pozostaly lug zostaje albo wprost uzyty do rozpuszczania przemytego langbeinitu, albo dopiero po uprzedniem ostudzeniu; w obu wypadkach po uprzed¬ niem zmieszaniu z macierzystym lugiem szenitowym z dodatkiem wody.Czesc pozostalych przy przeróbce ma¬ cierzystych lugów szenitowych odparowu¬ je sie w temperaturze powyzej 90° do za¬ wartosci okolo 40 g Cl w litrze, przyczem odzyskuje sie w postaci langbeinitu czesc K2SO±i który oddziela sie od lugu na go¬ raco, natomiast klarowny lug goracy studzi sie do temperatury okolo 25°, przyczemwydziela sie sól gorzka. Macierzyste lugi soli gorzkiej jyyiewa sie. PLIt is known to obtain the so-called calimagnesia from raw langbeinite, whereas according to the invention potassium sulphate and magnesium sulphate are produced from langbeinite. After grinding, crude langbeinite is freed from chlorides by washing with cold water. The thus washed langbeinite, almost free from chlorine, dissolves hot above 90 ° in a mixture of chenite and sulphate mother liquors with addition of water. The obtained hot langbeinite solution is freed from the slurry of ill, then it is cooled to a temperature of about 25 °, and chenite falls out of the solution. The chenite crystals separated from the liquor are mixed with water at a temperature of about 55 °, and potassium sulphate is lost. The resulting potassium sulfate, in the form of fine crystals, is separated from the mother liquor while hot. The remaining lug is either used directly to dissolve the washed langbeinite or only after it has been cooled beforehand; in both cases, after mixing with the mother chenite with the addition of water. Some of the mother chenites remaining in the processing are evaporated at a temperature above 90 ° to a value of about 40 g Cl per liter, and recovered as The langbeinite part of K 2 SO ± i which separates from the brown liquor, while the clear hot liquor is cooled to a temperature of about 25 °, while bitter salt is released. The mother lugs of bitter salt are eaten. PL
