Detailed explanation-1: -The only important use of chalcopyrite is as an ore of copper, but this single use should not be understated. Chalcopyrite has been the primary ore of copper since smelting began over five thousand years ago. Some chalcopyrite ores contain significant amounts of zinc substituting for iron.
Detailed explanation-2: -Uses: As a minor ore of copper and as mineral specimens.
Detailed explanation-3: -Chalcopyrite (/ˌkælkəˈpaɪˌraɪt, -koʊ-/ KAL-kə-PY-ryte, -koh-) 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.
Detailed explanation-4: -This is a plausible result given the conductivity and nature of both graphite and chalcopyrite: very good conductors with a threading / connecting habit; compared to pyrite which, in aggregate, is often a moderate, not very well-connected conductor (Emerson, 2019.
