Case study flowsheets: copper–gold concentrate

2005-1-1  The conventional treatment of copper–gold concentrates involves smelting, converting, and electro-refining to produce a copper-cathode product. The conventional treatment of copper–gold concentrates does elicit some compelling reasons to seek an alternative hydrometallurgical process for the recovery of concentrate values.
