Processing of potash ore

The hot leaching method of ore processing is based on the physicochemical properties of NaCl-KCl-H2O system. The main principle of this method is the different temperature-depending degree of solubility of the mineral components – sylvite and halite: the high solubility of potassium chloride from ore by cycling solution at 115°C and the further crystallization of the valuable component on ...

Arab Potash Company - Plants And Production Process

Heated brine returned from the crystallization stage is used for leaching the potassium chloride (KCl) solids. The hot KCl-saturated brine is clarified in a thickener, and then the overflow is pumped to the crystallization stage. The underflow slurry containing sodium chloride crystals is dewatered, repulped with waste brine and pumped to tailings.

Potash Flotation Process

Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the latter usually in the order of 1 to 1½%. 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.

This type of crystallisation is used to make ammonium sulfate from ammonia (either gaseous or liquid) and sulfuric acid, or MAP/DAP by reacting ammonia with phosphoric acid.

potash processing muriate

Potash is a general term used to describe a variety of K-containing fertilizers used in agriculture. Potassium chloride (KCl), the most commonly used source, is also frequently referred to as muriate of potash or MOP (muriate is the old name for any chloride-containing salt). Potassium is always present in minerals as a single-charged cation (K +).
