Copper heap leach development – not as easy as it looks. july . heap leaching has become increasingly popular in the copper industry for treating oxide and secondary sulphide ores, and is now being extended to primary sulphide ores. if you are thinking about a project, here are some practical pointers to help you towards a successful.Dec 12, oxide ore, 4% of recoverable copper, is crushed, agglomerated and then acid leached in large heaps and the copper is recovered from the leach solutions as copper.
Dump leaching is relatively cheap, so is commonly used for low grade ores. after a year or two, a typical low grade ore will yield ~50% of its metal in this way. dump leaching operations, if not done properly, can result in significant environmental.Extracting copper from other ores. copper can be extracted from non-sulphide ores by a different process involving three separate stages: reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(ii) sulphate.
