Magnesium sind im allgemeinen in Zinlterzen nur in sehr geringer Menge vorhanden und der Kalk ist unter b.) durch die Schwefelsäure fast zur Gänze a, Is Kalziumsulfat aus-
EMI2.1
säure wird durch den Kalk und das Blei des Erzes, welchem man, wenn nötig, Kalk zufügt, ausgefällt.
Hierauf beginnt die vorstehend geschilderte Reihe von Vorgängen von neuem.
Man könnte die Schwefelsäure zwischen den Operationen b.) und c.) durch Kalk ausfällen, doch müsste man sehr reinen Kalk nehmen. Ist nach einer gewissen Anzahl Operationen die Flüssigkeit an Mangan und Magnesium angereichert worden, so kann durch Destillieren nach Zusatz von Schwefelsäure eine salzfreie, wässerige Lösung von Essigsäure regeneriert werden. e. ) Das unter c.) erhaltene wasserhaltige Zinksulfid wird bei verhältnismässig niedriger Temperatur getrocknet und kann dann als Farbe benützt werden.
Wenn es die Zusammensetzung des Erzes erlaubt, so kann der unter a.) erhaltene Rückstand nach dem Trocknen und mahlen als Engelrot, Polierpulver u. s. f. in den Handel gebracht werden.

Magnesium is generally only present in very small quantities in tin ores and the lime is almost entirely eliminated by the sulfuric acid under b.) A, Is calcium sulfate.
EMI2.1
Acid is precipitated by the lime and lead of the ore, to which lime is added if necessary.
The series of processes described above then begins anew.
The sulfuric acid could be precipitated with lime between operations b.) And c.), But one would have to use very pure lime. If, after a certain number of operations, the liquid has been enriched in manganese and magnesium, a salt-free, aqueous solution of acetic acid can be regenerated by distillation after adding sulfuric acid. e. ) The water-containing zinc sulfide obtained under c.) Is dried at a relatively low temperature and can then be used as paint.
If the composition of the ore allows, the residue obtained under a.) Can be dried and ground as angel red, polishing powder and the like. s. f. be placed on the market.
