Carnallite processing using reverse flotation has been developed in recent decades. Khur Biabanak is the Iranian greatest Potash complex. Despite developments in the mineral processing technologies, common flotation systems which are used for potash flotation suffer from many disadvantages as high depreciation, wasteful energy usage and low production rate. In this project Jameson flotation cell is used and compared with current operating systems. In order to have an accurate comparison, a laboratory Denver cell is used in parallel. Under optimal circumstances for flotation of NaCl using Jameson cell recovery of 89.48% and grade of 83.24% are obtained. Concentration of Armoflote 619 as appropriate collector for NaCl flotation in optimum condition was 150 gr/ton and S/L ratio of 20% obtained as the best solid content. In the same situations in Denver cell 85.18% recovery for sodium Chloride with concentrate grade of 68.34% achieved as well.
