May 05, 2017 Leaching Chalcopyrite is the holy grail for hydrometallurgists Leachers, difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not 100 not leachable, not unusual for ore dumps low grade containing chalcopyrite to be placed under leach but report low recovery -30 TCu over several years and the rate is around 0.5-1 per month.
Fools Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden

Chalcopyrite is not easily oxidized, and it can maintain natural floatability for a long time in neutral and weakly alkaline pulps. However, in a strongly alkaline pH 10 slurry, since the surface is eroded by OH-, a hydrophilic iron hydroxide film is ...
A copper iron sulfide mineral, chalcopyrite ranges in color from a brass to golden yellow color, which may be highlighted in spots by an iridescent purplish tarnish. On the Mohs scale of hardness, it ranks between a 3.5 and a 4.
Chalcopyrite or copper pyrite, looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as Fools Gold because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.
