Continuous Flotation of High-Clay Potash Ores. | National …
The Bureau of Mines investigated the concentration characteristics of high-clay sylvinite ores from potash companies operating in the Permian Basin near Carlsbad, N. Mex. These ores, containing 14 to 19 percent K2O and 3 to 5 percent clay slimes, cannot be effectively processed by current commercial flotation methods because of their high-clay ...

OneMine | Flotation of Potash Ores
The most important type of potash ores, sylvinite, contains sylvite, halite and a small percentage of insoluble gangue [sulfates (anhydrite), carbonates (dolomite), and clay minerals]. Primary normal long-chain amines are exlusively utilized to float sylvite from halite, but since mines are also adsorbed by insoluble slimes, the process requires prior …
