The major factors include comminution circuit selection, heap leaching use, treatment of ores with high silver content, and flotation options for sulfides. Gold bearing ores that include basemetal mineralization, particularly copper, are classified as complex ores. These ores will often consume cyanide and create issues in CIP and elution.
