<p>This invention describes a production process of Ammonium Nitrate liquor derived from Ammonium Nitrate prills with cationic coating. The new process of the product preparation presented consists of three different steps described in this invention. In the first step, this nitrate with cationic coating is put in a container which is then heated with talc and water in order to act as ancillary binding agent in anti-caking. In the next step, this solution is mixed with a polymer solution in which the two solutions react giving rise to three different phases, that is, the liquor itself, the part with polymer and impurities that are drawn off and, thus, separated, and the part with polymer that forms an emulsion that separates by flotation. In the last step of the process here described, the drawn off part is removed by a discharge and the flotation elements are extracted by multiple titrations.</p> |
