Today, potassium salt manufacturers introduce the production methods and principles of potassium chloride! Let's take a look at it!

Production method of potassium chloride

According to the different potassium-containing resources of raw materials, the production methods of potassium chloride are mainly divided into two categories: one is extracted from solid potassium salt ore, the other is extracted from potassium-containing brine, and the latter is divided into two types, one is chloride-type potassium-containing lake brine, and the other is seawater.

The main production methods of solid potassium salt ore are cold decomposition-flotation method, cold decomposition-hot melt crystallization method and so on The production methods represented by liquid potash ore (mainly salt lake brine) mainly include cold decomposition-washing method, cold decomposition-flotation method, reverse flotation-cold crystallization method, insolation method, cold crystallization-positive flotation method, bittern blending-rapid controlled crystallization method, etc. In addition, there are sea salt bittern-bittern-bittern method and zeolite method, etc.

Production principle of potassium chloride

The production principle of potassium chloride is mainly to guide the production according to the phase diagram, and separate and extract potassium chloride after evaporation and crystallization according to the sequence of evaporation and precipitation of each component and the solubility difference at different temperatures. It is worth noting that solid potash ore must be transformed into solution by means of various solvents (mainly water), and then separated in the form of liquid phase, but its production should be guided according to the phase diagram in the separation process.
