摘要: The method of calcium nitrate production by treating limestone with the nitric acids, evaporation of the calcium nitrate solution, followed by cooling and crystallization of the product at the solid stage, characterized by the fact that the reaction process between nitric acids and the limestone is carried out in a reactor with a packing, and the concentration of the calcium nitrate solution is carried out until crystalline seeds come into being in situ. Next, the obtained crystallization suspension is cooled while microelements of the group: Cu, Fe, Mn, Zn are simultaneously added, which is followed by the formation, and the crystallization of the end product in a solid form of flakes.
