Acanthite: Mineral information, data and localities.

Acanthite is the low-temperature modification of silver sulphide. All natural silver sulphide specimens at room temperature are acanthite. The structure of Argentite, the high-temperature cubic (isometric) form cannot be quenched.At atmospheric pressure, pure argentite is stable above 177°C and acanthite is stable below 177°C.

Mining engineering - Wikipedia

Mining in the engineering discipline is the extraction of minerals from underneath, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying.A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral ...

Taconite - Wikipedia

Taconite (IPA: [''tækΙ™naΙͺt]) is a variety of iron formation, an iron-bearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate.The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik ...

Iron | Geoscience Australia

Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of ''alloys'' which are even stronger and don''t rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food cans to tools.

Antigorite: Mineral information, data and localities.

Al-Antigorite: An unnecessary name for an aluminium-bearing variety of Antigorite. Andes Jade: Marketing term for a tough lapidary-quality serpentine (composed dominantly of antigorite, with 21 to 31% lizardite, minor magnetite and Mg-carbonate) from Argentina.

Carbon dioxide - Wikipedia

Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth''s atmosphere as a trace gas.The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.

Coal, Metallic and Mineral Resources | WA - DNR

Mining of coal and metallic minerals in Washington began in the mid to late 1800s. Coal production in Washington hit a high in 2003 with an estimated total production of 6,232,000 short tons, yet production ceased in 2006. Metals mining during the same general time period occurred on both sides of the Cascade divide, but was largely concentrated in the northeastern portion of

Graphite: Mineral information, data and localities.

Named "plumbago" in 1739 by Magnus von Bromell, but in a different sense than previous authors such as Agricola and Conrad Gesner. Also called "molybdaena", but "molybdaena" was shown to represent two species, molybdenite and graphite - as known today, in 1781 by Carl Wilhelm Scheele. Named graphite in 1789 by Abraham Gottlob Werner from the Greek "graphein", "to write".
