Bartolomé De Medina (mining Specialist)
Bartolomé de Medina (born around 1504 in Seville) was a Spanish merchant known for his invention of the patio process. Biography In Europe, he learned the economics of litharge smelting, and, from a German man known only as "Maestro Lorenzo" or "Leonard", he learned how to efficiently use mercury, and a "strong brine", to extract silver from its ore. Around the age of 50, Medina moved to New Spain, leaving behind his wife Leonor de Morales and their five children. First settling in Mexico City, Medina worked on silver amalgamation for a year at the residence of Hernando de Ribadeneyra, before moving on to Pachuca. There, he built his ''Hacienda de Beneficio Nuestra Senora de la Purisima Concepcion'', which included paved surface ''patios'' on which he could spread ground ore. Located on Magdalena Mountain, he had access to running water and lower grade ore in the Old Discovery Mine dump. However, it was several months before Medina discovered that the brine and mercury method L ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chalcopyrite
Chalcopyrite ( ) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green-tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides, and sulfates. Associated copper minerals include the sulfides bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu2O). Is rarely found in association with native copper. Chalcopyrite is a conductor of electricity. Etymology The name chalcopyrite comes from the Greek words , which means copper, and ', which means striking fire. It was sometimes historically referred to as "yellow copper". Identification Chalcopyrite is often confused with pyrite and gold since all three of these minerals have a yell ...

16th-century Spanish Businesspeople
The 16th century begins with the Julian year 1501 ( MDI) and ends with either the Julian or the Gregorian year 1600 ( MDC) (depending on the reckoning used; the Gregorian calendar introduced a lapse of 10 days in October 1582). The 16th century is regarded by historians as the century which saw the rise of Western civilization and the Islamic gunpowder empires. The Renaissance in Italy and Europe saw the emergence of important artists, authors and scientists, and led to the foundation of important subjects which include accounting and political science. Copernicus proposed the heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the 1572 appearance of a Milky Way supernova. These events directly challenged the long-held notion of an immutable universe supported by Ptolemy and Aristotle, and led to major revolutions in astronomy and science. Galileo Galilei became a champion of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Georgius Agricola
Georgius Agricola (; born Georg Pawer or Georg Bauer; 24 March 1494 – 21 November 1555) was a German Humanist scholar, mineralogist and metallurgist. Born in the small town of Glauchau, in the Electorate of Saxony of the Holy Roman Empire, he was broadly educated, but took a particular interest in the mining and refining of metals. For his groundbreaking work ''De Natura Fossilium'' published in 1546, he is generally referred to as the Father of Mineralogy.Rafferty, John P. (2012). ''Geological Sciences; Geology: Landforms, Minerals, and Rocks''. New York: Britannica Educational Publishing, p. 10. He is well known for his pioneering work '' De re metallica libri XII'', that was published in 1556, one year after his death. This 12-volume work is a comprehensive and systematic study, classification and methodical guide on all available factual and practical aspects, that are of concern for mining, the mining sciences and metallurgy, investigated and researched in its nat ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Luís De Velasco
Luis de Velasco y Ruiz de Alarcón (1511 – July 31, 1564) was the second viceroy of New Spain during the Spanish colonization of the Americas in the mid-sixteenth century. Biography Velasco was born in the town of Carrión de los Condes, in the province of Palencia, in 1511. The son of a wealthy nobleman, Velasco received formal education at a young age. By 1547, he had become viceroy and leader of Spain's armed forces in the Kingdom of Navarre. Impressed with Velasco's achievements and loyalty to the Spanish crown, Emperor Charles V (King Charles I of Spain) sent him to New Spain, in 1550, to deal with problems in the Spanish colonies, among them slavery and the encomienda system. He was accompanied by his son, Luis de Velasco, marqués de Salinas, himself a future viceroy of New Spain. Velasco replaced the previous viceroy, Antonio de Mendoza. Mendoza had been given his choice of the Viceroyalty of Mexico or of Peru, with Velasco to fill the other office. Velasco ar ...

Don (honorific)
Don (; ; pt, Dom, links=no ; all from Latin ', roughly 'Lord'), abbreviated as D., is an honorific prefix primarily used in Spain and Hispanic America, and with different connotations also in Italy, Portugal and its former colonies, and Croatia. ''Don'' is derived from the Latin ''dominus'': a master of a household, a title with background from the Roman Republic in classical antiquity. With the abbreviated form having emerged as such in the Middle Ages, traditionally it is reserved for Catholic clergy and nobles, in addition to certain educational authorities and persons of distinction. ''Dom'' is the variant used in Portuguese. The female equivalent is Doña (), Donna (), Doamnă (Romanian) and Dona () abbreviated D.ª, Da., or simply D. It is a common honorific reserved for women, especially mature women. In Portuguese "Dona" tends to be less restricted in use to women than "Dom" is to men. In Britain and Ireland, especially at Oxford, Cambridge, and Dublin, the word is us ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Viceroy
A viceroy () is an official who reigns over a polity in the name of and as the representative of the monarch of the territory. The term derives from the Latin prefix ''vice-'', meaning "in the place of" and the French word ''roy'', meaning "king". He has also been styled the king's lieutenant. A viceroy's territory may be called a viceroyalty, though this term is not always applied. The adjective form is ''viceregal'', less often ''viceroyal''. The term ''vicereine'' is sometimes used to indicate a female viceroy ''suo jure'', although ''viceroy'' can serve as a gender-neutral term. Vicereine is more commonly used to indicate a viceroy's wife. The term has occasionally been applied to the governors-general of the Commonwealth realms, who are ''viceregal'' representatives of the monarch. ''Viceroy'' is a form of royal appointment rather than noble rank. An individual viceroy often also held a noble title, however, such as Bernardo de Gálvez, 1st Viscount of Galveston, who was ...

Pyrite
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Iron, FeSulfur, S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic Luster (mineralogy), luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek language, Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the pyrite group, sulfide minerals. Pyrite is usua ...

Gossan
Gossan (eiserner hut or eisenhut) is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein. In the ''classic'' gossan or iron cap all that remains is iron oxides and quartz, often in the form of boxworks (which are quartz-lined cavities retaining the shape of the dissolved ore minerals). In other cases, quartz and iron oxides, limonite, goethite, and jarosite, exist as pseudomorphs, replacing the pyrite and primary ore minerals. Frequently, gossan appears as a red "stain" against the background rock and soil, due to the abundance of oxidized iron; the gossan may be a topographic positive area due to the abundance of erosion-resistant quartz and iron oxides. Although most gossans are red, orange, or yellow, black gossans from manganese oxides such as pyrolusite, manganite, and especially psilomelane form at the oxidized portion of manganese-rich mineral deposits. In the 19th and 20th centuries, gossans were important ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
