Heap Leach Demonstration Plant | Bannerman Resources

Leach irrigation was conducted for 20 days followed by a post leach drain of 2 days and then a rinse and post rinse phase of 3 days and 5 days respectively. A weak sulphuric acid solution (2g/l) was used as rinse solution. Phase 3 of the Demonstration Plant work program entailed the closed circuit heap leach operation of three cribs.
