Ore deposits

Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.
The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost of extraction to determine whether it is of sufficiently hig

Mineral Extraction The Environmental Literacy Council

Longwall mining allows for increased mineral extraction to occur, since it shears entire blocks of mineral onto a conveyor belt through the use of selfadvancing, hydraulic roof supports or shields. Once the mineral is extracted, the supports move on and the roof is allowed to collapse.

Extraction of Resources Geology

Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay.

Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

AP Environmental Science Chapter 15 Flashcards Quizlet

Iron, copper, stone, and gravel are usually extracted by openpit surface mining, in which a giant hole is dug. In strip mining, a trench is dug to extract the minerals. Subsurface mining, which is underground, may be done with a shaft mine or a slope mine. A shaft mine is a direct vertical shaft to the vein of ore.

Copper Mining and Processing Processing of Copper Ores

B. Processing of Sulfide Ore. Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

What Are the Different Ways That Minerals Can Be Mined

Mining is the process of mineral extraction from an ore or rock seam. The minerals can range from precious metals and iron to gemstones and quartz. In ancient times, miners recognized a mineral rock formation from its outcrop at the surface.

Mineral Extraction an overview ScienceDirect Topics

Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface and groundwater pollution, erosion, and sedimentation. The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore.
