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. The ...

Peacock ore, or Chalcopyrite, pronounced kalcopieright (kal as in "calendar", "co" as in coat), is a copper iron sulfide mineral that crystallizes in the tetragonal system. The name "Chalcopyrite" is derived from the Greek words chalkos, "copper" and pyrites, "strike fire". It is normally brass yellow but may have a purplish blue tarnish.

Chalcopyrite is a copper iron sulfide (CuFeS 2) mineral with a brassy to golden yellow color (Fig. ). Chalcopyrite contains % Cu, % Fe, and % S. The mineral is the principal source of copper metal, and one of the major source of sulfur. The mineral also contains traces of elements of gold and nickel and recovered in refinery.

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).

Oxidation of chalcopyrite in air ( atm of O2 equilibrated with atmospheric water vapour) results in a Fe(III)OOH surface layer on top of a Cu rich sulfide layer overlying the bulk chalcopyrite with the formation of Cu(II) and Fe(III) sulfate, and Cu(I)O on prolonged oxidation. Cu2O and Cu2Slike species have also been proposed to ...
