BORNITE (Copper Iron Sulfide) Amethyst Galleries. Bornite is an important copper ore mineral. It ranks up there with many of the other copper ores such as chalcocite, chalcopyrite, covellite, digenite, cuprite and tetrahedrite.
Description: Chalcocite is formed either as a primary vein mineral or, more typically, in supergene deposits where it forms as a result of the redeposition of copper from the breakdown of minerals such as chalcopyrite or bornite.

Polished rock chip made from permian limestone with copper ore. Limestone with bornite (orange) and covelline (blue) Limestone with bornite (orange), chalcocite (blue), chalcopyrite (yellow).
Bornite, a copperore mineral, copper and iron sulfide (Cu 5 FeS 4). Typical occurrences are found in Mount Lyell, Tasmania; Chile; Peru; and Butte, Mont., Bornite, one of the common copper minerals, forms isometric crystals but is seldom found in these forms.
heap leaching of copper ores leaching oxidized copper ores effect of strength of acid in leaching Heap Leach Pad Design Because flow is downward in percolation leaching, the leach pad is the most important element of the solution containment system.
Copper Ore. Copper ore is the composite of copper's sulfide, oxide and other minerals. When reacting with vitriol, glaucous copper sulfate forms. Natural copper ore has various colors. Brass is bright yellow. Bornite is dark copper red and when it is oxidized, it would turn bluish violet. Chalcocite is lead gray while the copper sulphide is indigo blue.

chalcocite an overviewScienceDirect Topics. Selective flotation of Cusulfide minerals chalcopyrite, chalcocite, bornite from oxide recycled endofuse objects is about 15% of copperfromore copper .
Bornite is often mined as an ore of copper due its chemical composition of copper iron sulfide. Its streak results in grayish black, has a metallic luster, poor cleavage, Mohs Hardness scale score of to, and a specific gravity between and
dosage of mol/ton ore (a dosage equivalent to 20 g sodium ethyl xanthate per ton ore). A superior copper grade was obtained with the 90% ethyl xanthate:10% diethyldithiocarbamate collector mixture at a dosage of mol/ton ore compared to that obtained with ethyl xanthate at .
In large deposits of copper sandstones, chalcopyrite is accompanied by bornite and chalcocite (at Dzhezkazgan and Udokan in the USSR and the deposits of the Copperbelt of Central Africa). Concentrations of chalcopyrite in sedimentary rocks are usually low, but they may sometimes reach commercially acceptable levels in copper shales, for example, the Mansfeld ore field in the German .
Introduction of Shanxi Copper Ore Flotation Dressing Plant Xinhai. Apr 27, 2018 Flotation process is the common copper ore dressing method. And the content of bornite and chalcocite are increased at the upper part. technology to produce the final highquality copper, gold and silver concentrate.
As an ore of copper, the yield of chalcopyrite is rather low in terms of atoms per molecule. It is only 25%, compared to other copper minerals such as chalcocite, Cu2S 67%; cuprite, Cu2O 67%; covellite, CuS 50% or bornite Cu5FeS4 50%.
Other names for bornite may include blushing copper, erubescite, peacock copper, purple copper ore, and variegated copper. It is both a primary and secondary mineral often found in copper ore veins, mainly in hydrothermal metamorphic rocks and in mesothermal veins.
following three natural copper sulphides minerals: djurleite, chalcopyrite and bornite with %, % and % purity, respectively. The mineralogical and elemental compositions of these minerals are shown in Tables 1 and 2. Djurleite (Cu 31 S 16) has a chemical composition which is very similar to chalcocite (Cu 2 S).
Some examples include bornite (Cu 5 FeS 4), chalcocite (Cu 2 S), covellite (CuS), digenite (Cu 9 S 5), malachite Cu 2 CO 3 (OH) 2, and rare oxides such as cuprite (Cu 2 O). But, it is very rarely found with native copper (It is the uncombined form of copper which occurs as a natural mineral).

Bornite was named after Ignaz Edler von Born (1742–1791), a distinguished Austrian mineralogist. This mineral is also referred to as peacock ore.
