(PDF) Assesment of Ammoniacal Ammonium Sulpha te Leaching …
The test work leading to the introduction of ammonia in the industrial leaching plant is described. In the plant it was found that the extraction of copper was halved by the use of ammonia, thus leading to significant reductions in the amount of cyanide consumed in the full-scale leaching system. KEYWORDS Gold-copper ore treatment.

Case study flowsheets: copper–gold concentrate treatment
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.
