| abstract |
THE MANGANESE BIOXIDE ORE, IN THE FORM OF A FINELY GROUND POWDER, IS MIXED WITH A CAUSTIC POTASSE SOLUTION (KOH) OF CONCENTRATION NEAR 50, IN A KOHMNO MOLAR RATIO BETWEEN 2 AND 3. THE MIXTURE IS THEREFORE OBTAINED. NOW IN SUSPENSION BY AGITATION, IN AN ATOMIZATION 1 REACTOR OR CIRCULATES A CURRENT OF HOT AIR, WHICH CAUSES THE DEPOSIT, ON THE BOTTOM OF THIS REACTOR, OF A POWDER ESSENTIALLY CONSTITUTED OF POTASSIUM HYPOMANGANATE (KMNO) ET OF POTASSIUM MANGANATE (KMNO), AFTER WHICH THIS DRIED POWDER IS TRANSFERRED INTO A 2-PLATE REACTOR HEATED AND SUPPLIED WITH WATER AND OXYGEN, SO AS TO TRANSFORM THE POTASSIUM HYPOMANGANATE INTO POTASSIUM MANGANATE IN REACTORS MONANT, BOTH SERIES AND CONTINUOUS FEEDS. |
