This sample is from Copper Mountain, about 20 km south of Princeton in southern BC. I think you have chalcopyrite; but the easiest way to differentiate chalcopyrite from bornite when the specimen is massive is to determine its specific gravity (or density). Chalcopyrite Vs Bornite. The formation of bornite at the centre of the orebodies from Picachos is attributed to the pseudomorphic replacement of chalcopyrite or through its growth inside the chalcopyrite grains (Fig. It forms mainly in hydrothermal copper ore deposits with minerals such as chalcopyrite , pyrite marcasite , and quartz . For a long time it seemed that was the end of mining at Copper Mountain, but production resumed in 2011 and continues to this day. Chalcopyrite recovery was marginally improved from the collectorless flotation case while bornite experienced vastly improved recoveries in the presence of a collector to surpass the recovery of chalcopyrite. 1.15), often tarnished, with greenish-black streak and submetallic luster.The hardness varies between 3.5 and 4.0 on the Mohs scale. Chalcopyrite is the most common ore mineral for copper. Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. The most significant chalcopyrite deposits to be mined are hydrothermal in origin. As nouns the difference between covellite and bornite is that covellite is mineral a shiny indigoblue sulfide mineral, cusulfurs, that is an ore of copper while bornite is. if chalcopyrite contact with acids color may be develop red to blue to purple iridescence; Some weathered chalcopyrite is attracts attention and shops will sell it as “peacock ore”, which is actually bornite. They are Not the same, even though they have the same chemical structures. Here you see a piece of bornite with chalcopyrite on it. this being said, proper chalcopyrite would be a noticeable brassy color, and oftentimes proper untarnished bornite … (chalcopyrite) but during heating it reacts first to cubic intermediate solid solution (iss) and pyrite ... thetic bornite, CusFeSe, was used as a DTA calibrating material, and synthetic FeS, CuFeS, and CuFerSia were employed in some of the test work.

A big quartz vein mineralized with bornite and chalcopyrite, vein contains gold, silver, copper and lead values. Small amounts of bornite are also found disseminat… Ag2S formed on the surface because Cu and Fe in the chalcopyrite were replaced by Ag+, accelerating chalcopyrite dissolution and enrichment of Ag on the surface of the chalcopyrite. After chronoamperometry at 0.70 and 0.80 V vs. SHE, respectively, for 6 and 2 h, analyses by using S-SAXRD revealed peaks of bornite on oxidized chalcopyrite electrodes. 4d). chalcopyrite. The Bornite structure is CuFeS 4, while the Chalopyrite structure is CuFeS 2. Copper sulfides are a closely related mineral group, and they often occur together. It was named from the Greek word for “Copper” and “Brass”, and can most notably be seen as shades of yellow, green and grey. Soc. It is widely spread copper–iron sulfide mineral with chemical formula (CuFeS 2).The color is typically brass to golden-yellow (Fig. if chalcopyrite contact with acids color may be develop red to blue to purple iridescence Zhao et al. A way to tell the difference between bornite and acid-treated chalcopyrite is to use a streak plate; bornite streaks dark gray and chalcopyrite streaks a green tinged black. Chalcopyrite is enhanced with acid to produce bluish–purple Peacock Ore stone. I think you need an expert on chalcopyrite. Clearly, they are not the same and their healing powers are different. Chalcopyrite [CuFeS 2] is a copper iron sulfide that is often confused with the iron sulfide, pyrite [FeS 2]. It is also known as peacock ore because of its iridescent purple-blue-green tarnish. The healing properties are not the same. In this bornite specimen are also bits of golden metallic chalcopyrite (CuFeS 2) and areas of dark-gray chalcocite (Cu 2 S). Fresh bornite, however, is copper red. So, you were able to "scrape" it, but not cut it? The most important use of chalcopyrite is an ore of copper for five thousand years. After chronoamperometry at 0.70 and 0.80 V vs. SHE, respectively, for 6 and 2 h, analyses by using S-SAXRD revealed peaks of bornite on oxidized chalcopyrite electrodes.
