IMPROVED LEACHING OF BASE METALS

摘要

A method for the leaching of base metals from oxide ores, the method characterised by the method steps of: a) Separating the ore to be leached into fine and coarse fractions or streams; b) Leaching the coarse fraction of the ore in a leach solution with a suitable leach agent for the leaching of the contained metals; and Utilising the fine ore fraction or part thereof to neutralise or partially neutralise the leach agent contained in a pregnant leach solution produced in step b), prior to passing some or all of the pregnant leach solution on for further refinement or other treatment as required.
