Underground uranium mining is in principle no different from any other hard rock mining and other ores are often mined in association (, copper, gold, silver). Once the ore body has been identified a shaft is sunk in the vicinity of the ore veins, and crosscuts are driven horizontally to the veins at various levels, usually every 100 to 150 metres.
You can stand right at the south rim of the Mission openpit copper mine and watch the mining operation in progress when you visit the Mineral Discovery Center. If you start your tour about a halfhour before the 4:00 shift change, you might get to see an actual mine blast.
It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silicabearing flux. The silica flux binds with the iron and other impurities and keeps them separated from the copper and iron fall to the bottom of the furnace like a molten metal rain, while the sulfur combines with oxygen to form sulfur dioxide gas.
The direction that treatment and refining charges take will largely depend on the success of additional copper smelter capacity being brought online, but it clearly presents an opportunity for onsite hydrometallurgical processing of copper concentrates. The recent recovery in copper metal prices has been followed by a dramatic rise in smelter
Early Bronze and Copper Technology From the Dawn of History Until Early Historic Times (2000 B. C. 400 B. C.) Anthropologists speak of the Copper Age, the Bronze Age, and the Iron Age as steps or stages through which societies and cultures pass in the course of .
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 ores are extracted by either traditional mining (open pit or underground) or by leaching. The copper is then recovered using physical and chemical techniques.

The copper is used in many applications. Copper is strong, and has excellent thermal and electrical properties. It is used mainly in electrical wiring (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is present in our homes, our cellphones, our computers and our cars – the average car contains km of copper wire.
The copper market moved with the economy, hitting a bottom with the depression and panic of 1893 only to rebound after 1896. During the mid1890s Thomas Weir and Newhouse emerged on the scene, primarily in the Bingham Canyon area, and brought copper mining and .
6. Refining. Copper from the smelter is melted and cast as anodes, the solution from the solvent extraction process moves to a plating operation.

Apr 25, 2013· Mining and Refining of Copper – How Stuff Works Copper ore is mined both underground and on the surface. Large excavations formed by surface mining are called openpit mines.
The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath. When jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of . They float to the surface making a froth.
