beneficiating copper oxide ores prior to leaching

Mining and Metallurgy - Blogger

Uranium ore is mined in several ways: by open pit, underground, in-situ leaching, and borehole mining. Low-grade uranium ore typically contains 0.1 to 0.25% of actual uranium oxides, so extensive measures must be employed to extract the metal from its ore. High-grade ores found in Athabasca Basin deposits in Saskatchewan, Canada can contain up ...

Unlike sulfide ore, the beneficiation of oxide ore involves acid leaching, where the copper is liberated by the addition of sulfuric acid. The liquor, commonly known as PLS (pregnant leach solution), is an acidic, metal-laden liquid that needs to be clarified - or beneficiated - to separate the leached copper.
