Occurrence of Sn-Bearing colusite in the ore-body “T” of the Bor copper deposit, Serbia

The ore body “T” is the newly discovered massive-pyrite type one which is located in the central part of the Bor copper mine. The main copper minerals are chalcocite-digenite, covellite and enargite. Small amounts of colusite are frequently present in the ore-body. It mostly occurs as the distinct e...

Description
Summary:The ore body “T” is the newly discovered massive-pyrite type one which is located in the central part of the Bor copper mine. The main copper minerals are chalcocite-digenite, covellite and enargite. Small amounts of colusite are frequently present in the ore-body. It mostly occurs as the distinct exsolutions in digenite and, associating with enargite and covellite. Composition of the studied colusite shows enriched Sn content, giving an empirical formula from Cu 24.7 V 1.8 Fe 0.2 As 5.1 Sb 0.2 Sn 0.8 S 32 to Cu 26.7 V 2.0 Fe 0.3 A s3.0 Sb 0.3 Sn 3.5 S 32 . This colusite represents a solid solution between colusite and nekrasovite within a range of 14–54 mol % nekrasovite. Most of the analyses show content of
