potassium ore production process

Processing of potash ore

The processing of potash ores by hot leaching with further crystallization of potash salt from saturated salt brines (halurgical method) began in XIX century in Strasburg. The primary methods of potash ore processing are flotation (mechanical method) and hot leaching (chemical method).

Process for producing potassium manganate

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/MnO 2 between 2 and 3. The resulting suspension is fed continuously to an atomization dryer and then to a plate dryer.
