Passivation of sulfidic iron-containing rock |
摘要 |
A method for passivating sulfidic iron-containing rock comprising: contacting sulfidic iron-containing rock with a magnesium-containing substance, a manganese-containing substance, and a calcium-containing substance; and adjusting the pH of the system to below about 11, is provided. The method can be used to prevent acid rock drainage of metal-bearing rocks or to produce a pretreated ore or rock which can be contacted with a lixiviating agent to extract metals from the pretreated ore or rock.
