Beginners guide to thickeners
Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...

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 reduced the ...
Specific ion binding interactions in potash flotation
Abstract. As the main resource of potash fertilizer, high grade of sylvite (KCl) is mainly separated from halite (NaCl) in soluble potash ores using flotation. An effective flotation collector determines the separation efficiency of sylvite. However, the collector adsorption mechanism is still the subject of much debate due to high ions ...

FERTILIZER
POTASH The liberation of potash is site-specific. In some cases, potash particles liberate with very high grade at over 3-mm. In other cases, good liberation is achieved at finer sizes (i.e., passing 0.500-mm). As a result, plant circuitry can vary to a large degree. Plants may or may not include a coarse flotation circuit depending on the
Removal of insoluble slimes from potash ore by air
In this regard, air-sparged hydrocyclone (ASH) flotation was examined as a process alternative for the removal of such insoluble slimes from potash ores. The effects of reagent concentration and ASH operating variables on the recovery of insolubles were studied for a typical plant feed from the Saskatchewan potash field.
