Carnallite Flotation of Khur Biabanak Potash Complex using …
necessary to remove the halite from the carnallite ore before decomposition. In this work, a flotation method was developed using kimiaflot 619 as a collector for flotation of halite and sylvite from carnallite. A new collector was synthesized for carnallite flotation and compared with Armoflot 619. The 1-bromooctadecane (C 18H

The lowest flotation selectivity was observed for the fine-grained ore sample (0.1–0.25 mm). The combined ultrasonic treatment of this sample during conditioning and flotation approximately halved the recovery of NaCl in the potash concentrate (from 17.9 % to 9.9 %) and increased the KCl recovery from 89.9 % to 95.9 %.

Wang et al. utilized alkyl morpholine as the halite collector in the reverse flotation of halite from carnallite, with a grade of KCl in the final product of 86–92% (Wang et al., 2014). Nevertheless, the reverse flotation method is only suitable for purifying potassium salt ores with a low halite content, limiting its application.
