The cost of refining oil using the conversion process is somewhat higher than the extraction process. This extra cost incurred by the refiner is eventually passed on to the customer. However, in this case, the customer typically gets what he pays for - a higher quality base oil at a higher initial price.

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.

This liquid containing the minerals is then pumped out of the ground and the mineral can then be recovered by various techniques. C. Extraction ("Mining it") In the extraction stage the mineral is removed from the earth in large quantities as the mine begins producing. This stage is typically what we envision when we think of mining.

Extraction Process of Pegmatite Minerals

the branches of science and technology that embrace the processes of extracting minerals from the interior of the earth. For thousands of years mining was limited to the extraction of only solid minerals (nonmetallic construction materials, ore, and so on).

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...

Extractive metallurgy - Wikipedia

Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface water and groundwater pollution, erosion, and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into ...

UBM is engineering the natural processes of extremophiles used in metal extraction of certain types of mineral ores. Classical and contemporary molecular biology techniques are used to manipulate organisms to suit the needs of particular mining operations. In addition, novel molecules are being investigated that resolve various extraction issues seen in the industry.

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. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
