Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any
In-Situ Leach (ISL) Mining: Some ore bodies, due to ore concentration or the surrounding material, can only be accessed by dissolving the ore body using water soluble acids or alkalis and then pumping out the solution. The ore body is then recovered as a precipitate. This method is common when extracting minerals near aquifers.
LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.
Mechanical extraction methods employ mechanical processes in a dry environment to recover minerals, encompassing the specific mining methods of: Open pit mining is the most common method for large-scale operations, whereas underground mining is generally the most .

Methane monitor — An electronic instrument often mounted on a piece of mining equipment, that detects and measures the methane content of mine air. Mine development — The term employed to designate the operations involved in preparing a mine for ore extraction. These operations include tunneling, sinking, cross-cutting, drifting, and raising.
Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery. These systems are based on the property of diamonds having a much higher specific gravity (density) of ~3.52 g/cm3 compared to most of the other minerals that make up material in which diamonds are found.
Phosphate Mining. Extended mines and new mining operations undergo exhaustive planning and approval processes to protect air, water, ecology, transportation, safety and other environmental, health and public welfare considerations. After mining, state-approved reclamation programs will result in productive land uses,
Gold Extraction Recovery Processes. Heap leaching can be considered as a percolation process on ore piles. The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is
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.
The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process,
2 When a site is selected for mining, shafts are sunk into the center of the salt deposit. Then a machine that looks like a gigantic chain saw is used to cut a slot about 6.0 inches (15 cm) high, about 66 feet (20 m) wide, and about 10 feet (3 m) deep into the salt at floor level. This process is known as undercutting.
Chemicals used in mining and processing minerals contaminate the land, water, and air, causing health problems for workers and people living near mines. Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore
While the SX/EW process was adopted by the industry to take benefit from the sulfuric acid that the smelting process produced steps are being take to divorce the two. The Phelps Dodge Mining Company, for example, at its Morenci, Arizona mine, has completely disassembled its smelter and has converted the mine to a mine-for-leach operation.
Sand Mining / Dredging. Sand mining and dredging is critical to infrastructure development around the globe. It is used in the manufacturing of abrasives, concrete and is mixed with salt to use on icy roads. Sand dredging can extract various minerals that contain useful elements like titanium. Sand mining can also be used in the replacement of eroded coastline.
Gold Mining Process And Techniques For Mining Gold Modern gold mining processes are largely the same techniques used in gold mining for hundreds, if not thousands, of years. The modern processes for mining gold use larger equipment and more refined techniques, but essentially it still the same principles as has always been used.
Data mining technology is something which helps one person in their decision making and that decision making is a process where in which all the factors of mining is involved precisely. And while involvement of these mining systems, one can come across several disadvantages of data mining

This is through faraway the generally commercial industry as well as generate the lions input of exports wages for the nation once integrated by means of source mining industry such that lubricate oil and gas. Australia have enormous minerals of products like aluminium natures gas, 
Copper Applications in Metallurgy of Copper Copper Alloys. 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 the world's largest (in terms of output) open-pit copper mine, Escondida.
