Method for preparing nickel aminosulfonate from nickel carbonate and solid sulfamic acid

The invention discloses a method for preparing nickel aminosulfonate from nickel carbonate and solid sulfamic acid, and belongs to the technical field of nickel-containing chemical production. The method comprises the following steps: directly adding solid sulfamic acid into pulpified nickel carbonate to generate acid-base neutralization reaction, thereby preparing a high-concentration nickel aminosulfonate solution; and evaporating, crystallizing, centrifuging and drying the nickel aminosulfonate solution to obtain a nickel aminosulfonate product. The method adopts single preparation raw materials, is simple in process, does not add substances such as a catalyst, avoids side reaction caused by initiator adding, improves purity of a nickel aminosulfonate product, obtains the high-concentration nickel aminosulfonate solution, shortens evaporation time, reduces production cost and increases the yield. 本发明公开了种利用碳酸镍和固体氨基磺酸制备氨基磺酸镍的方法，属于含镍化学品生产技术领域。该方法首先将固体氨基磺酸直接加入到浆化的碳酸镍中发生酸碱中和反应，制备出高浓度的氨基磺酸镍溶液，然后将该氨基磺酸镍溶液依次经过蒸发、结
