The flotation chemistry of potassium double salts ...

It is known from soluble salt flotation practice that the K, Mg double salts of kainite (KClMgSO 4 3H 2 O), and carnallite (KClMgCl 2 6H 2 O) are difficult to float and must be converted to other salts such as ite (K 2 SO 4 MgSO 4 6H 2 O) and sylvite (KCl) in order to recover potash values. The flotation characteristics of these double salts have now been confirmed in …

Potassium Chloride - an overview | ScienceDirect Topics

Froth flotation of the surface-sensitized pulp by vigorous aeration and agitation in saturated brine (density ca. 1.18 g/mL), first in a series of "rougher" cells with further refinement in "cleaner" units, produces a stable froth consisting almost entirely of beneficiated potassium chloride and an underflow of sodium chloride (particle ...

Potash Flotation Process

Flotation has been developed as the principal separating process for the potash salts which generally are coarsely crystalline and free from the sodium salts at about 10 to 14 mesh. In most cases the potash is floated in the froth product and the salt, NaCl, discarded as tailings.

Celanese - The chemistry inside innovation

However, the froth flotation process is also used to extract coal, iron, potassium chloride, phosphates, and – in the paper recycling industry – for deinking paper fibers. While the froth flotation process certainly can require significant investment – in equipment, specialty chemicals, etc. – it offers significant flexibility to the ...

We claim: 1. In a method for the production, by froth flotation, of potassium chloride with a K 2 O content of >55 wt. % from the fine salt obtained during the decomposition of carnallite or of potash salts containing carnallite, and consisting essentially of the potassium chloride formed during the decomposition process, natural sylvite and kieserite, following conditioning of decomposition ...

In the process of separating sylvinite into its components potassium chloride from sodium chloride by froth flotation, in which potassium chloride is recovered in the tops and sodium chloride is left in the bottoms, the potassium chloride yield is increased, and its contamination with sodium chloride diminished, by the pressure of a sodium chloride crystal habit modifier in the flotation system.
