The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open pit 90 of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make

CSIRO Team Leader, Dr David Miljak, said the ore sorter is likely most suited to the copper mining industry as it can detect these minerals at extremely low grades. He believes the processing costs for a big mining operation will drop radically for each pound of copper or ounce of gold produced as much as 20 in some mines.

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mininges prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on

How Mining Works What you need to know about underground mining. A look at the underground mining process . The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Heres how it works. Ore, rock

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. El Teniente, in Chile, is the world's largest

Underground Mining. Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead

Depending on how these ores are extracted, mining methods can be categorized as surface or underground types. In surface mining, the rock barrier on top of the deposit is removed to access the ore. However, sometimes, such deposits occur too far below to access them from the surface. In such cases, they are extracted by leaving the overlying rock intact, and accessing the deposit

The mining methods to be employed at T 17 Underground are Transverse and Longitudinal CAF mining. The Transverse CAF mining method consists of the main access drive longitudinally developed to the ore body. From the main access drive, stope drives are developed perpendicular to the main access drive. The stope drives are widened to create stopes, leaving a pillar between adjacent stopes.
