Abstract
The present invention relates to a process for obtaining and refining elemental iodine contained in an iodide solution, which specifically comprises the steps of iodide cutting, and iodine melting, which take place simultaneously by reacting the preheated iodide solution with an oxidizing agent for directly producing elemental molten iodine, without passing iodine through a crystalline state; and the step of separating elemental molten iodine from spent melt water by liquid-liquid separation; carrying out all these steps in a single system operated in continuous regime.
