There are four main mining methods underground, open surface (pit), placer, and in situ 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.
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.
Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. Open pit mining is the preferred method for mining gold, silver, and uranium. This type of mining is also used to dig for coal and building stone. Cost.

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.
Extraction of Copper. Copper is sometimes found as native metal. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
Technologies in Exploration, Mining, and Processing INTRODUCTION The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use.
Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec ades of this century, whenopen pit mining, flo tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching solvent extrac tion electrowinning, the basic methods
Seafloor mining has the potential to minimize the impact of copper mining by producing more copper with fewer natural capital inputs, fewer damaging outputs and a smaller area of impact. 5.

Copper is typically found deep within the crust of the earth, and both underground mining and open pit mining techniques are used in order to properly extract copper from these location. There are two different types of ore deposits that are estimated to contain 80% of the worlds copper supplies.
Summary of Molycorp's Green Mining Methods Molycorp increased funding to these sectors of research and development and reported allotting $8.3 million towards these areas in 2011. Although not all of the technology is in use yet, this research helped develop some of the new technology listed above (Molycorp Annual Report, 2012).
Copper mining market can be segmented on the basis of mining methods used Open pit copper mining is the predominant method used for extraction due to Resources , BHP Billiton , Codelco, and Bougainville Copper Limited.
Probably. Early smelting methods at that time were crude and inefficient by the standards of today. Copper smelting and to a lesser degree copper mining produced ultra fine particle dust that was carried into the atmosphere on air currents created by the intense heat from smelting operations.
One major environmental problem with mining ores is what to do with the spoil (waste material from the mining) as this contains traces of the ore which is often toxic. When it rains, traces of the metals can leach out. This leaching can spread the toxic waste more widely into the environment. An example of this is from lead mining in Derbyshire.

The copper is recovered by electrolytic refining. Advantages of this process are much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper for this reason, leaching extraction is growing in importance.

Traditional mining, also known as old school mining, is a mining method involving the use of simple manual tools, such as shovels, pickaxes, hammers, chisels and pans. It is done in both surface and underground environments. Until the early 1900s, traditional mining was widely used throughout the world.

Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
The advancements made in mining equipment, such as those achieved at General Kinematics, along with mining technology progress have resulted in growth and production in the copper mining industry. From primitive, cumbersome mining methods to compact, efficient modern day equipment, copper mining has become a cost effective, efficient process.
