Sodium dodecyl benzene sulfonate (SDBS) was developed to separate picromerite and halite as collector. The flotation tests showed that SDBS could separate picromerite from halite, the K + recovery was 95.64 % and Na + content was 1.42 % at SDBS dosage of 300 g/t. DFT calculations revealed that SDBS tended to adsorb on picromerite ( …
