Open pit mining is a technique used to extract copper ore near the earth''s surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth''s surface.
Copper is a major metal and an essential element used by man. Copper ore is extracted using two basic methods of mining open pit or underground mining. 3. Processing of Copper Ore. The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces.
Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; 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.
Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world''s largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and relatively near the surface, where they can be quarried after removal of overburden. Chile also boasts
Openpit mining. Openpit mining is probably most advanced because of developments in mining lowgrade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow lowcost removal of most of the resource.
From primitive, cumbersome mining methods to compact, efficient modernday equipment, copper mining has become a costeffective, efficient process. Additionally, todays mining equipment makes it possible to reduce waste and decrease chemical exposure during all phases of the copper mining
Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Open pit copper mining plants usually comprise two major components, the open pit mining operation and the copper ore enrichment plant. An open pit copper mine is an excavation or graze made into the surface of the ground for the purpose of extracting ore.
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks
Openpit Mining Openpit mining, also known as opencast mining, opencut 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
