Oct 19, 2021 · In all cases, the sulphide ores were treated by conventional milling followed by flotation producing a gold/copper concentrate and cyanide leaching of the flotation tails to produce doré.
copper recovery [1]. With liberated and copperassociated gold readily recovered in the flotation stage, this recovery difference is often due in part to operating strategies that require rejection of goldbearing iron sulphide gangue minerals in order to maintain a saleable copper concentrate grade. To minimise gold losses, it is a common ...
fore gold in an alkaline glycine solution followed by washing and gold leaching either using the same process at elevated temperature (40–60 °C), as patented by the authors, or using a cyanidation process. Copper selective leaching will reduce the gold losses due to a cementation mechanism of gold in the presence of metallic copper as all ...
