bornite वाक्य

The "'Bornite Range "'is a subrange of the Bulkley Ranges, located just northeast of Terrace on the north side of Kleanza Creek in northern British Columbia, Canada.
When viewed under a microscope in plane polarized light, skaergaardite appears to be bright creamy white ( in the presence of bornite or chalcopyrite ) or bright white ( in the presence of digenite or chalcocite ).
The supergene sulfide zone is present from about 35 to 65 m in depth and has significant copper enrichment, with predominantly chalcocite, and lesser digenite, covellite, and bornite, along with pyrite, minor pyrrhotite, anglesite, and gangue minerals.
Associated copper minerals include the sulfides bornite ( Cu 5 FeS 4 ), chalcocite ( Cu 2 S ), covellite ( CuS ), digenite ( Cu 9 S 5 ); carbonates such as malachite and azurite, and rarely oxides such as cuprite ( Cu 2 O ).
As an example the Palabora complex of South Africa has produced significant copper ( as chalcopyrite, bornite and chalcocite ), apatite, vermiculte along with lesser magnetite, linnaeite ( cobalt ), baddeleyite ( zirconium-hafnium ), and by-product gold, silver, nickel and platinum.
