Misión Santa Rosalía De Mulegé
Mission Santa Rosalía de Mulegé is located in the oasis of Mulegé, in Mulegé Municipality, northeastern Baja California Sur state, México. It is an Instituto Nacional de Antropología e Historia listed Cultural Heritage Monument. Etymology The mission is named after both Saint Rosalia and the indigenous Cochimí settlement of Mulegé. History The mission was founded in 1705 by the Jesuit missionary Juan Manuel de Basaldúa and financed by the Marqués de Villapuente at a ranchería of the local Cochimí people known as ''Mulegé'', on the eastern Baja California Peninsula, in Viceroyalty of New Spain. The site lies near the entrance of Bahía de Concepción, on the coast of the Gulf of California. A hurricane in 1717 devastated the agricultural fields that supported the original settlement. Construction of a stone church was begun in 1766. In 1768, when the Franciscans took over responsibility for colonial Baja California from the Jesuits, there were reportedly still ...

Manganese
Manganese is a chemical element; it has Symbol (chemistry), symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber additive, and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese is commonly found in labo ...

Manto Ore Deposit
A polymetallic replacement deposit, also known as carbonate replacement deposit or high-temperature carbonate-hosted Ag-Pb-Zn deposit,Megaw, P.K.M., Ruiz, J., and Titley, S.R., 1988, High-Temperature, Carbonate-Hosted Ag-Pb-Zn(Cu) Deposits of Northern Mexico: Economic Geology, v. 83, pp.1856-1885 is an orebody of metallic minerals formed by the replacement of sedimentary, usually carbonate rock, by metal-bearing solutions in the vicinity of igneous intrusions. When the ore forms a blanketlike body along the bedding plane of the rock, it is commonly called a manto ore deposit. Other ore geometries are chimneys and veins. Polymetallic replacements/mantos are often stratiform wall-rock replacement orebodies distal to porphyry copper deposits, or porphyry molybdenum deposits.Ray, G., Webster, I., Megaw, P., McGlasson, J., and Glover, K., 2001, The Lustdust Property in Central British Columbia: A Polymetallic Zoned Porphyry-Skarn-Manto-Vein System: British Columbia Geological Survey Ge ...

Zinc
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second most abundant trace metal in humans after iron, an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt
Cobalt is a chemical element; it has Symbol (chemistry), symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal. Cobalt-based blue pigments (cobalt blue) have been used since antiquity for jewelry and paints, and to impart a distinctive blue tint to glass. The color was long thought to be due to the metal bismuth. Miners had long used the name ''kobold ore'' (German language, German for ''goblin ore'') for some of the blue pigment-producing minerals. They were so named because they were poor in known metals and gave off poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), which was ultimately named for the ''kobold''. Today, some cobalt is produced sp ...

El Boleo
El Boleo is a copper-cobalt-zinc-manganese deposit located adjacent to the port city of Santa Rosalía, Baja California Sur in Mexico. It includes a historic open pit copper mine, as well as underground workings. Mining began in the 1860s, and continued, off and on, until the 1980s. The property is currently under development by a consortium of Korean companies led by Korea Resources Corporation. Preliminary underground mining began in 2012. The project cost $1.75 billion, and mining began in the first half of 2014. Copper production began on January 17, 2015. The mine has an estimated life of 22 years. History Early history The discovery of the copper ore in the region is historically credited to a rancher named José Rosas Villavicencio in 1868. Minor mining activities were carried out on site by Mexican and German operators until 1885. But the small scale of the operation and the desolate location made the enterprise only marginally economic. Compagnie du Boleo El Boleo ...

Locomotive
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...

Metallurgical Converter
Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the ''Bessemer converter''. Modern steel mills use basic oxygen process converters. Equipment The converting process occurs in a ''converter''. Two kinds of converters are widely used: horizontal and vertical. Horizontal (which are an improvement of the ) prevail in the metallurgy of non-ferrous metals. Such a converter is a horizontal barrel lined with refractory material inside. A hood for the purpose of the loading/unloading operations is located on the upper side of the converter. Two belts of tuyeres come along the axis on either sides of the converter. Molten sulfide material, referred to as matte, is poured throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverberatory Furnace
A reverberatory furnace is a metallurgy, metallurgical or process Metallurgical furnace, furnace that isolates the material being processed from contact with the fuel, but not from contact with combustion gases. The term ''reverberation'' is used here in a generic sense of ''rebounding'' or ''Reflection (physics), reflecting'', not in the acoustics, acoustic sense of ''echoing''. Operation Chemistry determines the optimum relationship between the fuel and the material, among other variables. The reverberatory furnace can be contrasted on the one hand with the blast furnace, in which fuel and material are mixed in a single chamber, and, on the other hand, with crucible, Muffle furnace, muffling, or Retort, retort furnaces, in which the subject material is isolated from the fuel and all of the products of combustion including gases and flying ash. There are, however, a great many furnace designs, and the terminology of metallurgy has not been very consistently defined, so it is ...
