NUOVO PROCEDIMENTO PERL'OTTENIMENTO DEL MANGANATO DI POTASSIO, (K2MNO4) PER LA FABBRICAZIONE INDUSTRIALE DELPERMANGANATO DI POTASSIO (KMNO4) APARTIRE DAI MINERALI NATURALI OPPURE DAI COMPOSTI DEL BIOSSIDO DI MANGANESE.

摘要

Potassium manganate is produced by mixing finely ground manganese ore with a solution of potassium hydroxide (having a concentration of about 50% W/V) in a mole ratio KOH/MnO2 between 2 and 3. The resulting suspension is fed continuously to an atomization dryer and then to a plate dryer.
