Methods And Machines Used For Open Pit Mining Of Copper

Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is obtained by using traditional methods such as underground mining and open pit mining, with the latter method accounting for 90% of the ore used in smelting.

Copper Mining and Processing Everything you Need to Know

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using todays compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, its roasted, which helps to convert sulfides to oxides.

Bingham Canyon, Copper Mine, Utah, USA Mining

The resources were studied for extraction by open pit mining methods. However, because of the economic downturn, the option to expand the underground operations was suspended. Rio hoped to begin the project in 2009 and produce copper valuing about $22.67bn at the prevailing prices. A major molybdenum deposit was discovered in 2008.

Open Pit Mining TechniquesSurface MinesRock or Mineral

Open pit mining, also known as opencast mining, open cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
