METHOD FOR SEPARATING AND COLLECTING TIN INSIDE VARIETY OF COMBINED METALS

摘要

Disclosed is a method for separating tin from a variety of combined metals and collecting same. The method for separating and collecting tin from the variety of combined metals according to the present invention, comprises: a leaching step of introducing tin into a solubility increasing agent for increasing the solubility inside the catalyst of tin (IV) ions, which uses a variety of combined metals to which at least one different metal having a lower ionization tendency compared to tin is combined as an oxidizing agent, and uses tin ions to leach the tin from the variety of combined metals, and then settling the different metal; a solid-liquid separation step of separating the different metal in a solid state from the solvent in which tin is dissolved after the leaching step; and a collection step of collecting tin from the solvent.
