Hence, hardness is often the easiest way to distinguish between these two minerals. Chalcopyrite is a relatively soft mineral and may be scratched by a nail or knife blade, whereas pyrite is harder than most metal implements. Gold: Gold is much softer than pyrite, does not exhibit crystals, and is a very malleable material (easily shaped).

Chalcopyrite is essentially unleached under the mild oxidizing conditions of heap leaching (very slow leach kinetics). It can, however, be leached under oxidizing conditions at elevated temperatures or by microbial leaching under lowpotential conditions (Gericke, Govender, Pinches, 2010).This has led to extensive study into leaching of chalcopyrite concentrates as an alternative to smelting.

The lowgrade chalcopyrite contained high content of alkaline gangue, which consumed acid and led to the increase of pH. To alleviate the adverse effect of high pH on chalcopyrite bioleaching (Wang et al. 2018a), the pH was daily adjusted to ± before day 112 and then the adjustment frequency was changed to once every 3 days.
