    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 schoenite (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 detail by.The Froth Carry Rate (FCR) and is expressed as t m2h the amount of material that 1m2 of froth can carry to the launder lip in an hour In a flotation cell the froth surface area is determined by the amount of froth crowding Designing a flotation cell with a low froth surface area (high degree of froth.
