EXPLORING HPGR TECHNOLOGY FOR HEAP LEACHING

2014-10-1  Understanding the leach extraction and therefore the lowest cut-off grade that can be fed to a HPGR heap leach circuit is obviously important. Establishment of the upper and lower boundary and variability of the gold grade and recovery window defines the feed limitations. Across a resource, both measures are crucial to project economics. Characteristics that promote the application of HPGR prepared Heap Leach processing for large tonnage projects are presented in the paper. Of note is the potential dual use of the crushing circuit for both the main CIL/P plant and the heap leach.

Hydrometallurgical Processing of Low-Grade Sulfide Ore

2018-10-7  If leaching at Udokan is carried out only during warm season (140 days per year), leaching of ore with below 400 mm grain size will take 5–7 years. In case of a year-around operation with solution heating, the leaching will take 2–3 years. The SX/EW process is considered to be the most suitable method for copper extraction.
