sulfide ore beneficiation

ANDRITZ thickening solutions for beneficiating oxidized ...

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.
