This reduction of the content of sodium chloride potassium chloride and apparatus for implementing it.

摘要

The present invention relates to a process for reducing the content of sodium chloride potassium chloride, characterized in that it forms an aqueous suspension of crystals of potassium chloride, on the power supply having a wide particle size distribution, about 0,1 to about 50 μm in diameter, in a solution saturated with potassium chloride, products which have a lower content of sodium chloride crystals that said power supply and which have a mean diameter of about 10 to about 1000 times greater than the mean diameter of said crystals. / p & & p & the present invention also relates to a process for the purification of potassium chloride, by reducing the concentration of sodium chloride.
