4. Biogenic sulphide for cyanide recycle and copper recovery 4.1. Sulphide-based processes for cyanide and copper recovery In the SART process, the cyanide associated with the copper (and zinc, if present) cyanide complexes is released, allowing it to be recycled back to the leach process as free cyanide.

Malononitrile was comparable to equal molar quantities of sodium cyanide in leaching gold from oxide ore and yielded 10–20 % higher recovery in leaching a refractory carbonaceous ore, although dissolution was slower with malononitrile than with cyanide (Heinen et al., 1970). Nitriles are also toxic, but they are far less harmful than cyanide.

Microwave processing enhanced the grindability of the ore, and crushing strength was reduced by 31.2%. The presence of micro-cracks improved leaching rate, and over 95% extraction was achieved within 12 h as against 22 h for the non-microwaved sample. Such a strategy can be used to maximize recovery and man-hours on …
