Dotychczas do oddzielenia kizerytu stosowano metode prze¬ mywania polegajaca na rozpuszczeniu chlorku sodowego. Ujemna cecha tej metody jest ko¬ niecznosc odprowadzania znacznych ilosci od¬ cieków solankowych i niska wydajnosc procesu.Przedmiotem wynalazku jest sposób otrzymy^ wania kizerytu za pomoca flotacji, eliminujacy ujemne cechy metody przemywania. W sposo- ; bie wedlug wynalazku proces flotacji kizerytu prowadzi sie w zawiesinie soli po rozkladzie karnalitu i oddzieleniu KC1 w, nasyconym lugu *) Wlasciciel patentu oswiadczyl, ze wspól¬ twórcami wynalazku sa Edward Buntner, Maria Klimek, Stanislawa Nowak, Jerzy Najda i Ha¬ lina Hilarowicz. karnalitowym lub lugu nasyconym wzgledem soli porozkladowej.Zawiesine odpowiednio rozdrobnionej (w za¬ leznosci od struktury kizerytu) pozostalosci po¬ rozkladowej poddaje sie dwustopniowej flo¬ tacji ciaglej. Wysokoprocentowy koncentrat po wysuszeniu i prazeniu stanowi techniczny siar¬ czan magnezu, który moze byc wprost uzyty lub przerobiony na tlenek i inne sole magnezo¬ we. Jako lug flotacyjny stosuje sie lugi o du¬ zym stezeniu chlorku magnezowego lub so¬ lanke nasycona chlorkiem potasowym i chlor¬ kiem sodowym z niewielka zawartoscia siar¬ czanu magnezowego i chlorku magnezowego.Lug flotacyjny utrzymuje sie w obiegu uzu¬ pelniajac jedynie straty.

Mieszanine te wprowadza sie w sposób ciagly do systemu komór flotacyjnych, zebrany koncentrat pianowy flotuje sie po¬ wtórnie w komorach oczyszczajacych, a odpad po flotacji wtórnej zawraca do flotacji wstep¬ nej. Oczyszczony koncentrat po odsaczeniu, przemyciu i wysuszeniu zawiera 95—99% kize¬ rytu. Odzyskanie kizerytu w koncentracie wy¬ nosi 70-80%.\ Lug flotacyjny znajduje sie w obiegu. PLPublished on August 31, 1960. w4l% leTpirpr-j - * -: -: POLSKIEJ RZECZYPOLITEJ PEOPLEJ PATENT DESCRIPTION No. 43392 KI. , 12 m, L Institute of Inorganic Chemistry *) 'Gliwice, Poland The method of obtaining magnesium sulphate from the residues after the processing of carnallite-kieserite salt The patent has been in force since May 16, 1959 Solid waste obtained as a result of the processing of carnallite-kieserite salt, consisting mainly of kieserite (MgSO 4 · H 2 O) and rock salt can be used as a starting material for the preparation of kieserite. Until now, a washing method involving the dissolution of sodium chloride has been used to separate the kieserite. The disadvantage of this method is the need to discharge large amounts of saline effluents and the low efficiency of the process. The invention relates to a method of obtaining kieserite by means of flotation, which eliminates the disadvantages of the washing method. In a way; According to the invention, the process of kieserite flotation is carried out in a salt suspension after decomposition of carnallite and separation of KCl in a saturated slurry *). The patent owner stated that the inventors were Edward Buntner, Maria Klimek, Stanislawa Nowak, Jerzy Najda and Hilarowicz Hilarowicz. carnallite or slime saturated with respect to decomposition salt. The suspension of suitably crushed (depending on the structure of kieserite) decomposition residue is subjected to a two-stage continuous floatation. After drying and calcining, the high-percentage concentrate is technical magnesium sulfate, which can either be used directly or made into oxide and other magnesium salts. The float used is liquor with a high concentration of magnesium chloride or a brine saturated with potassium chloride and sodium chloride with a small content of magnesium sulphate and magnesium chloride. The float is kept in circulation, replenishing only the losses. Flotating factors are higher acids or alkylsulfonic alcohols, their salts or mixtures. If necessary, the addition of foaming or depressants may be used. Example. 100 kg of the wet residue after the separation of potassium chloride with a composition of approximately 30% kieserite, 64% rock salt, 3% potassium chloride, 2% magnesium chloride and 1% insoluble particles, is wet ground into grains with a diameter of less than 0.5 mm. is carried out in saturated carnallite slurry at 25% slurry density and mixed with the flotation reagent sodium marsolate or petepone G in the form of a 1% suspension in water at a rate of 1 kg / ton of flotation sediment. This mixture is continuously introduced into the flotation cell system, the collected froth concentrate is re-flotated in the cleaning chambers, and the secondary flotation waste is returned to the primary flotation. The purified concentrate, after filtering, washing and drying, contains 95-99% of kizerite. The recovery of kieserite in the concentrate is 70-80%. The flotation lug is in circulation. PL
