Potash is extracted from the earth by underground or solution mining. Over 50 million tons of sylvite (KCl) is produced annually from potash ore, primarily by the flotation process. Flotation involves the use of long-chain primary amines as collector for the flotation of KCl from NaCl and MgCl2 (Cao, 2010).
