    • PURPOSE: A method for leaching impurities contained in molybdenum oxide concentrates is provided to economically produce the molybdenum oxide concentrates with the superior quality by selectively leaching impurities from the molybdenum oxide concentrates using leachate. CONSTITUTION: A method for leaching impurities contained in molybdenum oxide concentrates includes an impurity leaching process with respect to the molybdenum oxide concentrates using leachate selected from a group including a first leachate, a second leachate, and a third leachate. The first leachate includes ammonium chloride, sodium chloride, hydrochloric acid, and water. The second leachate includes ammonium chloride, calcium chloride, hydrochloric acid, and water. The third leachate includes ammonium chloride, sodium chloride, calcium chloride, hydrochloric acid, and water.

    • PURPOSE: A method for leaching impurities contained in molybdenum oxide concentrate is provided to minimize the chemicals remaining in the molybdenum oxide concentrate and stably lower the fineness of copper in produced molybdenum oxide concentrate. CONSTITUTION: A method for leaching impurities contained in molybdenum oxide concentrate comprises the steps of: leaching impurities in oxidation molybdenum concentrate using a leaching liquid including ammonium chloride and hydrochloric acid, separating the leaching liquid from the oxidation molybdenum concentrate, and washing the separated oxidation molybdenum concentrate with water, wherein the oxidation molybdenum concentrate is obtained by roasting raw ore of molybdenum and the leaching liquid comprises ammonium chloride 5~20 weight%, hydrochloric acid 8~20 weight%, and water 50~300 weight%.
    • 目的:提供一种浸出氧化钼浓缩物中所含杂质的方法,以使残留在氧化钼浓缩物中的化学物质最小化,并稳定降低生成的氧化钼浓缩物中铜的细度。 构成:用于浸出氧化钼浓缩物中所含杂质的方法包括以下步骤:使用包括氯化铵和盐酸的浸出液将氧化钼精矿中的杂质浸出,将浸出液与氧化钼精矿分离,并洗涤分离的氧化钼 用水浓缩,其中通过焙烧钼矿原矿获得氧化钼精矿,浸出液含有5〜20重量%的氯化铵,8〜20重量%的盐酸,50〜300重量%的水。
