  • Mining copper: About 200 years ago the UK was an important world source of copper and there were mines in Cornwall and Wales. These mines have now closed and today the biggest copper mines are in Chile and North America. These produce many thousands of tonnes of copper ore per year. The main ores of copper are: chalcopyrite bornite malachite.

  • The largest deposit of nearly pure chalcopyrite ever discovered in Canada was at the southern end of the Temagami greenstone belt where Copperfields Mine extracted the high-grade copper. Of the copper ore mined in the United States, the majority is produced in three western states: Arizona, Utah, and …

  • Chalcopyrite, CuFeS 2, is the dominant copper mineral in these ores, with small amounts of another copper mineral, cubanite, CuFe 2 S 3. Some gold, silver, and the six platinum-group metals also are present, and their recovery is important.

  • The most significant chalcopyrite deposits to be mined are hydrothermal in origin. In these, some chalcopyrite occurs in veins and some replaces country rock. Associated ore minerals include pyrite, sphalerite, bornite, galena, and chalcocite. Chalcopyrite serves as the copper source for many secondary mineral deposits.

  • Bornite, also known as chalcopyrite or peacock ore, is a sulfidemineral. It got this name from its blue and purple colors when ittarnishes. Iron ore is not generally mined within towns, as most ...
