Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.

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 with Quartz from Tincroft Mine, Pool, Illogan, Redruth, Cornwall An excellent and classic example from the Tincroft Mine. A group of well defined crystals on a perfectly sized matrix.
Chalcopyrite has a golden yellow color, which often resembles Gold.However, its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it. Chalcopyrite is a beautiful mineral, with good crystals being fairly common.
Vein pyrite, however, may reveal the presence of other valuable minerals, such as chalcopyrite and gold. In the recent past, pyrite was mined as a sulfur source for sulfuric acid, an essential commodity for chemical industry.
Chalcopyrite Group. Chalcopyrite-Eskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may ...
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 ...

"Chalcopyrite Mine" is a producer unknown deposit site in the Rocky Mountain System of Montana, The United States. It is a deposit, located in the Colorado (Corbin-Wickes) District mining district and is not considered to be of world-class significance. 1 Copper deposits are documented at "Chalcopyrite Mine."
However, chalcopyrite is much more abundant than the other copper-bearing minerals and is far more widely distributed so it remains our most important copper source. In many societies copper was the first known metal to be widely worked, and for over six thousand years copper mining …
Chalcopyrite deposits mined that are hydrothermal in origin are the most significant, with some of the mineral occurring in veins and some replacing country rock. The minerals commonly associated with chalcopyrite include pyrite, bornite, chalcocite, galena, and sphalerite.
Copper is widely distributed in the environment; present mainly in minerals as sulphides, oxides, or carbonates, with the major ores being chalcopyrite (CuFeS 2), chalcocite (Cu 2 S), cuprite (Cu 2 O), and malachite (Cu 2 CO 3 (OH) 2). Copper was the first metal to be worked by human societies and is thought to have been mined for around 5000 ...

Mining: Sulfide minerals are the ore minerals for most commercially mined metals including Gold, Silver, Platinum, and Copper. Chalcopyrite is commonly mined alongside these more precious metals and is in fact the single most important Copper ore.
90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. 2. Leaching. The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. ... Chalcopyrite: Malachite: Bornite:
