The Case for Glycine Heap Leaching - mpsinnovation.au · PDF-bestand

Copper oxide minerals leach readily under GlyLeach conditions. Copper sulphides also leach, but at a slower rate, consistent with a heap leach operation. Gold also dissolves slowly in GlyLeach. The rate may be increased by catalysis with cyanide, or by increasing temperature to around 60C.

Automating and Optimizing Copper Heap .

Alena opens describing the heap leaching process for copper: Copper ore is excavated from the ground, crushed and then spread in uniform layers on a pad. A slow trickle of sulfuric acid is distributed over the pile, where it percolates to the bottom and a collection point. The acid leaches out the copper.

Heap Leaching Oxide and Sulfide Copper OresDeze pagina vertalen

In the heap-leaching method, crushed or uncrushed oxidized copper ore is placed on a prepared drainage pad. Acid leach solutions are distributed over the top of the heap, caused to percolate downward through the ore bed by gravity, and are drained from its base. The leach duration is generally a matter of a few months.
