WebJan 1, 2024 · Amidst transition metal sulfides (TMS), CuFeS 2 is a rarely reported non-precious TMC for supercapacitor application. The structure of CuFeS 2 can be considered as a double sphalerite cell with an ordered arrangement of Cu and Fe ions in the lattice, which is in tetrahedral coordination with sulfur [19]. phil michaels

Chalcopyrite - Properties, Formation, Uses and FAQs

WebHere, we report that, by alloying only 3% of In on the Cu sites of the diamond-like lattice of CuFeS 2 chalcopyrite compound (Cu 1–x In x FeS 2, x = 0.03) has a disproportionally large effect in reducing the lattice … Chalcopyrite is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green-tinged black. On exposure to air, … See more The name chalcopyrite comes from the Greek words chalkos, which means copper, and pyrites', which means striking fire. It was sometimes historically referred to as "yellow copper". See more Natural chalcopyrite has no solid solution series with any other sulfide minerals. There is limited substitution of zinc with copper despite … See more Chalcopyrite is present with many ore-bearing environments via a variety of ore forming processes. Chalcopyrite is present in volcanogenic massive sulfide ore deposits and sedimentary exhalative deposits, formed by deposition of … See more Copper metal is predominantly extracted from chalcopyrite ore using two methods: pyrometallurgy and hydrometallurgy. The most common and commercially viable method, pyrometallurgy, involves "crushing, grinding, flotation, smelting, refining, and electro … See more Chalcopyrite is often confused with pyrite and gold since all three of these minerals have a yellowish color and a metallic luster. Some important mineral characteristics that help distinguish these minerals are hardness and streak. Chalcopyrite is … See more Chalcopyrite is a member of the tetragonal crystal system. Crystallographically the structure of chalcopyrite is closely related to that of zinc blende ZnS (sphalerite). The unit cell is twice as … See more Even though Chalcopyrite does not contain the most copper in its structure relative to other minerals, it is the most important copper ore since it can be found in many localities. Chalcopyrite ore occurs in a variety of ore types, from huge masses as at See more WebNo information found for this chemical equation.
