| 摘要 |
<p>The present invention relates to a leaching method that enables the production of good quality molybdenum oxide concentrates by selectively leaching impurities such as copper, iron, lead and zinc from roasted molybdenum oxide concentrates using a leach liquor comprising ammonium chloride and hydrochloric acid. As molybdenum oxide concentrates produced by the leaching method of the present invention are mostly present in the solid state, a process for recovering molybdenum dissolved in the leach liquor is not required.</p> |
