1. introduction. pyrite is the most abundant sulfide in the earth’s crust and is also a major constituent of hydrothermal mineralization in a wide variety of ore systems including porphyry copper deposits volcanogenic massive sulfide deposits iron-oxide–copper–gold deposits sedimentary-hosted copper/uranium deposits archean to mesozoic lode epithermal and carlin-type gold deposits
chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ r aɪ t -k oʊ-/ kal-ko-py-ryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. it has the chemical formula cufes 2.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 chalcopyrite oxidises to a variety of oxides hydroxides

porphyry copper deposits are currently the world's largest source of copper and molybdenum and are also among the largest reservoirs of gold in the upper crust. despite the fact that pyrite is a ubiquitous mineral phase in these deposits and secondary cu enrichment processes are commonly controlled by the abundance of this sulfide the major and trace element chemistry of pyrite from porphyry
