hot leaching process flotation production potassium chloride kcl

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 ...
