Is this chalcopyrite treated with acid? How can I tell?

As far as I know, chalcopyrite (and bornite as well) are never found with that amount of colorful tarnish in nature. It has to be acid treated. The natural tarnish is much more dull and less varied in hue. AutoModerator • 4 yr. ago Hi, u/Walking_Stick1! This is a reminder to flair this post in r/whatsthisrock after it has been identified!

Chalkopyrit – Wikipedia

Chalkopyrit, veraltet auch als Kupferkies, Gelbkies, pyrites aureo colore oder geelkis bekannt, ist ein sehr hufig anzutreffendes Mineral aus der Mineralklasse der „Sulfide und Sulfosalze" mit der chemischen Formel CuFeS 2.Die Verbindung besteht also aus je einem Teil Kupfer und Eisen sowie zwei Teilen Schwefel und ist damit chemisch gesehen ein

Bioleaching of copper from chalcopyrite ore by fungi

In the present study bioleaching of copper from its low-grade chalcopyrite ore using 26 isolates of acidophilic fungi is reported. Most of these fungal strains belonged to the genera Aspergillus, Penicillium and Rhizopus. The leaching experiments were conducted in Czepek Dox minimal medium containing 1% (100 mesh) ore with shaking at room temperature

Sphalerite: The primary ore of zinc and a collector's

The chemical formula of sphalerite is (Zn,Fe)S. It is a zinc sulfide containing variable amounts of iron that substitutes for zinc in the mineral lattice. The iron content is normally less than 25% by weight. The amount of iron

A new synthesis scheme of pyrite and chalcopyrite reference

At the optimized conditions (600 C for pyrite, 400–600 C for chalcopyrite), the PAS-synthesized sulfides have a smooth surface and dense structure that are suitable for laser ablation analysis. Repeated measurements of Fe isotope and S isotope conducted on the PAS-synthesized pyrite and chalcopyrite by LA-MC-ICP-MS yielded highly consistent

Enhancing the Leaching of Chalcopyrite Using Acidithiobacillus

Chalcopyrite is the richest copper sulfide mineral in the world, but it is also the most resistant to biohydrometallurgical processing. To promote the bioleaching of chalcopyrite, a nonionic surfactant, t-octyl phenoxy polyethoxy ethanol (Triton X-100), was employed in this paper.

STRUCTURAL AND ELECTRONIC PROPERTIES OF CHALCOPYRITE

The chalcopyrite structure can be obtained by doubling the zinc-blende struc-ture along the z-axis and filling the lattice sites . The anions remain at their sites and every second (001) plane is occupied by cations as shown in Figure . In consequence, each C anion is coordinated by two A and two B cations and each cation is tetrahedrally coordinated by

Chalcopyrite is a minor accessory mineral of limited occurrence. It is commonly associated with sphalerite, galena, bornite, calcite, and other minerals, in both fine-grained and coarse-grained assemblages, occurring mostly in the Paleozoic sulfide veins. Masses up to 10 cm are known. Reflected-light studies by [Dunn] reveal that tennantite
