Ortiz Mountains
The Ortiz Mountains are a mountain range in northern New Mexico, United States, in Santa Fe County, northeast of the Sandia Mountains and due north of the San Pedro Mountains. The Ortiz include Placer Peak, the highest peak in the range at 8,858 feet, Lone Mountain at 7,310 feet, Cedar Mountain at 7,041 feet, Cerro Chato at 6,965 feet, and the foothills known as the Los Lomas de la Bolsa. New Mexico State Road 14 passes through the northwestern portion of the Ortiz Mountains between the towns of Golden and Madrid. Geology The Ortiz Mountains are on the east side of the Rio Grande Rift, with the Santa Domingo Basin and Hagan Basin of the rift to their west, with the Sandia uplift to the southwest, and the Espanola Basin and the Estancia Basin to the east. They form part of the watershed boundary between the Rio Grande and the Pecos River. The Ortiz Mountains are part of the larger Ortiz porphyry belt of Santa Fe County, and consist of late Eocene to early Oligocene intrusive ...

Placer Mining
Placer mining () is the mining of stream bed deposits for minerals. This may be done by open-pit mining or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup in Canada. The containing material in an alluvial placer mine may be too lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of New Mexico
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

Shrublands
Spring Park is a small area in London, England. It is within the London Borough of Bromley and the London Borough of Croydon, straddling the traditional Kent-Surrey border along The Beck. Spring Park is located north of Addington, London, Addington, west of West Wickham and south of Monks Orchard and Shirley, London, Shirley. History The area was historically known as Cold Harbour. Settlement began in the area in the 1830s at the instigation of the MP John Temple Leader, who employed the agricultural innovator Hewitt Davis to turn what was barren heathland into productive farmland. Large scale residential building began in the 1920s–1930s. The Shrublands council estate was constructed after the Second World War on compulsorily purchased land from the golf course. The area contains a small row of shops at the junction of Bridle Road and Broom Road. The Goat pub, which closed in 2017 following an attack on a local asylum seeker, re-opened in 2019 as The Apple Tree. Notable resi ...

Artemisia (genus)
''Artemisia'' ( ) is a large, diverse genus of plants belonging to the daisy family, Asteraceae, with almost 500 species. Common names for various species in the genus include mugwort, wormwood, and sagebrush. Some botanists split the genus into several genera, but DNA analysis does not support the maintenance of the genera ''Crossostephium'', ''Filifolium'', ''Neopallasia'', ''Seriphidium'', and ''Sphaeromeria''; three other segregate genera—''Stilnolepis'', ''Elachanthemum'', and ''Kaschgaria''—are maintained by this evidence. Occasionally, some of the species are called sages, causing confusion with the ''Salvia'' sages in the family Lamiaceae. ''Artemisia'' comprises hardy herbaceous plants and shrubs, which are known for the powerful chemical constituents in their essential oils. ''Artemisia'' species grow in temperate climates of both hemispheres, usually in dry or semiarid habitats. Notable species include '' A. vulgaris'' (common mugwort), '' A. triden ...

Adit
An adit (from Latin ''aditus'', entrance) or stulm is a horizontal or nearly horizontal passage to an underground mine. Miners can use adits for access, drainage, ventilation, and extracting minerals at the lowest convenient level. Adits are also used to explore for mineral veins. Although most strongly associated with mining, the term ''adit'' is sometimes also used in the context of underground excavation for non-mining purposes; for example, to refer to smaller underground passageways excavated for underground metro systems, to provide pedestrian access to stations (pedestrian adits), and for access required during construction (construction adits). Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the ad ...

Heap Leaching
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to In situ leach, in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas ''in situ'' mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates at a lower cost compared to conventional processing methods such as flotation, agitation, and vat leaching. Additionally, dump leaching is an essential part of most copper mining operations and determines the quality grade of the produced material along with other factors Due to the profitability that the dump leaching has on the mining process, i.e. it can contri ...

Consolidated Gold Fields
Consolidated Gold Fields was a British gold-mining company. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index until it was acquired by Hanson in 1988. History Consolidated Gold Fields of South Africa was founded in 1887 and incorporated in London to fund the newly discovered gold reefs in the Transvaal. By 1900 it had already started to diversify outside South Africa. After 1945 it acquired mines in the United States and Australia. Until the 1970s, it was predominantly a mining finance house receiving income from passive investments. In 1970 A.R.O. Williams O.B.E, who was then Managing Director, retired. After the 1970s it transformed itself into natural resource group concentrating on a relatively small number of minerals. The company had three major wholly owned subsidiaries: Amalgamated Roadstone Corporation, Gold fields Corporation and ARC America, both in the United States. By the late 1980s it was considering withdrawing from South ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
