Potash is the main source of Potassium which is one of the three basic plant nutrients along with nitrogen and phosphorus Between 60 to 80 of the potash ore is processed by flotation the other two important unit operations are hot or cold crystallization and electrostatic separation Almost all the published literature on potash flotation refers to the insoluble minerals as …
The separation of sylvite KCl and halite NaCl two main minerals in potash ores is difficult because of the high ion concentration fine particles of NaCl and aggregation of KCl and NaCl in the saturated system This study employed ammonium chloride NH4Cl as a new depressant and dodecyl morpholine as a collector in the reverse flotation process The depressing …
Currently over 80 of the world s potash is produced by the selective flotation of KCl from NaCl and other gangue minerals using long-chain C16-C22 aliphatic chains amine collectors as
It is known from soluble salt flotation practice that the K Mg double salts of kainite KClMgSO 4 3H 2 O and carnallite KClMgCl 2 6H 2 O are difficult to float and must be converted to other salts such as ite K 2 SO 4 MgSO 4 6H 2 O and sylvite KCl in order to recover potash values The flotation characteristics of these double salts have now been confirmed in some …
