  Heap Leaching of Gold and Silver Ores - ScienceDirect

  201611 · The oxide zone of massive sulfide ore deposits may contain gold and silver in iron oxides. Typically these are very soft and permeable, so crushing below 75 mm often does not increase heap leach recovery. The Filon Sur ore body at Tharsis, Spain, and the Hassai Mine, Sudan, are successful examples of heap leaches on this type of ore.

  Polymetallic sulfide flotation of gold ore - 911 Metallurgist

  5  · I have been involved in assaying a rock pit with sulfide ore for a couple of years. We have done gravity concentration tests and the ore loses 75% of the gold and silver value when you gravity concentrate. We did a down and dirty flotation test with biodiesel and successfully produced 33 opt gold concentrate.

  Sulfide Ore Concentration and Treatment - 911 Metallurgist

  2018515 · Milling Circuit. A flexible milling flow sheet was developed for a grinding circuit capable of processing both oxide and sulfide ores. Initially, the design utilized the existing heap leach ore crusher to provide 4,536 tonne/day (5,000 ton/day) of feed stock for a single-stage grinding circuit. The broad range of work indices of the different ...
