PURPOSE: An apparatus for dissolving impurities is provided to eliminate metal impurities from metal silicon and to minimize the amount of water required for diluting leachate by minimizing remaining leachate in dissolved metal silicon. CONSTITUTION: An apparatus for dissolving impurities includes a storing part(10), a mixing part(20), and a filtering part(30). The storing part stores leachate. The mixing part mixes silicon and leachate. Metal impurities included in the silicon are dissolved to be separated by the mixing. The mixing part collects the leachate. The filtering part solid-liquid separates the leachate and the metal impurities. The storing part includes storages(11, 12, 13) and a tank(17). The storages store at least two acidic solutions. The tank stores the leachate in which the acidic solutions and water are mixed. |
