Beschreibung
Zusammenfassung:	FIELD: fertilizers. ^ SUBSTANCE: invention relates to manufacturing fertilizers, in particular, potassium chloride with distinctive color. Method involves coloring flotation potassium chloride with suspension containing iron oxide pigment and sodium meta-silicate with addition of water to provide the uniform distribution of pigment of surface of salt crystal. Treatment is carried out using moisture material before its drying. Product treated with suspension into mixer is fed to dying and treated then with anti-caking solution and dust-suppressing agent. Invention provides preparing flotation potassium chloride stained with red-brown color with the high fixation degree of dye on surface of crystals. ^ EFFECT: improved coloring method. ^ 3 cl, 1 tbl
