Accounting for more than 70% of global copper reserves chalcopyrite CuFeS 2 is the most abundant copper bearing resource and is also widely distributed in solid wastes and secondary resources Panda et al 2012 The crystal structure of chalcopyrite is provided in Fig 1 de Oliveira and Duarte 2010 In 1917 chalcopyrite CuFeS 2 was named by Burdick and
1 Introduction Porphyritic copper molybdenum ores are the main mining resource for chalcopyrite and pyromorphite which account for about 50% of global production of pyromorphite and 75% of global production of copper [1] [2] Due to the excessive use of lime which has led to issues like pipeline jamming environmental disruption poor selectivity foam
Chalcopyrite is a mineral and ore of copper Its chemical composition is CuFeS2 meaning it contains copper Cu iron Fe and sulfur S Chalcopyrite is one of the most important copper ores and is widely distributed in various geological environments It is often found in association with other sulfide minerals
Chalcopyrite CuFeS 2 is the primary source of commercial copper metal Buckley and Woods 1984 Copper finds application in various fields such as power generation construction agriculture etc and its global demand is projected to constantly rise due to its essential role in modern technologies Schipper et al 2018 Enrichment of chalcopyrite and
The pyrrhotite ore came from the Dal N gorsk Primorsky Kray Mine Far Eastern Region Russia and the chalcopyrite ore came from the Casapalca Mine Huarochiri Province Peru Powder X ray diffraction XRD confirmed the identity and integrity of both minerals and revealed the pyrrhotite to be monoclinic Mineral composition and purity were
To date chalcopyrite is the commonest examined copper ore due to its inertness and global abundance indexes Out of between 150 and 180 global copper ores chalcopyrite is the most stabilized copper ore due to its structural configuration [1 2] It is mostly found in association with pyrite FeS 2 bornite Cu 5 FeS 4 sphalerite ZnS chalcocite Cu 2 S covellite CuS
Jetti Resources and the University of British Columbia have published new scientific research that underpins Jetti s technology for enabling copper production from low grade primary sulfide ores
