A method is useful for reducing the caking tendency of potassium chloride during storage thereof, wherein caking of the potassium chloride grains is induced in the potassium chloride, the caked potassium chloride is passed to grinding, and the ground potassium chloride is subsequently put into storage.

A method for producing potassium chloride granulates from a crystalline potassium chloride raw material. The potassium chloride raw material is treated, prior to granulation, with at least one alkali metal carbonate and at least one phosphate additive selected from alkali metal monophosphates, alkali metal pyrophosphates, linear alkali metal polyphosphates and mixtures thereof, in the presence of water.

Process and station for stabilizing an aqueous solution of an iron salt of an organic acid with a ferric component and a ferrous component of less solubility than the ferric component, such as the aqueous solution based on the Fe.sup.3+ salt of meso-tartaric acid. To stabilize the content of the dissolved ferric salt, the solution is at least partly subjected to electrolytic oxidation.
