In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock.Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation.The hydraulic flow involved is usually due to hydrothermal circulation.. Veins are classically thought of as being the result of growth of crystals on the walls of planar fractures in ...
Minerals are all around you. They are used to make your house, your computer, even the buttons on your jeans. But, where do minerals come from? There are many types of minerals, and they do not all form in the same way. Some minerals form when salt water on Earth's surface evaporates. Others form ...
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.

About Mining and MineralsThe Mining Law, as amended, opened the public lands of the United States to mineral acquisition by the location and maintenance of mining claims. Mineral deposits subject to acquisition in this manner are generally referred to as "locatable minerals." Locatable minerals include both metallic minerals (gold, silver, lead, copper, zinc, nickel, etc.)
The Harmful Effects of Mining. While mining provides us with the minerals we need, it is also very destructive because it disrupts the landscape both on the surface and underground.
Surface mining is a generic term describing several methods of mining mineral deposits from the surface, which entails removing the vegetation, top soil, and rock (called overburden materials) above the mineral deposit, removing the deposit, and reclaiming the affected land for postmining land use.

In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and ...
Mineral A mineral is a naturally occurring inorganic element of compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Minerals may be metallic, like gold, or nonmetallic, such as talc. Coal, oil, and natural gas are generally considered to be "energy minerals.

Finding and Mining Minerals. Geologic processes create and concentrate minerals that are valuable natural resources. Geologists study geological formations and then test the physical and chemical properties of soil and rocks to locate possible ores and determine their size and concentration. A mineral deposit will only be mined if it is profitable.
