Flotation of Insoluble Slimes from Potash Ore
Filtration of the insoluble slimes flotation concentrates recovered 87 to 90 percent of the brine. Flotation concentrate filtration rates were 7 times faster than the filtration rates of mechanically deslimed products. Potash losses in the deslime product and process brine requirements increase as the insol content increases.
