Cinnabar, or cinnabarite, is the bright scarlet to brick-red form of mercury(II) sulfide (HgS). It is the most common source ore for refining elemental mercury and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments.
The Viceroyalty of Peru, officially known as the Kingdom of Peru, was a Spanish imperial provincial administrative district, created in 1542, that originally contained modern-day Peru and most of the Spanish Empire in South America, governed from the capital of Lima. Peru was one of the two Spanish viceroyalties in the Americas from the sixteenth to the eighteenth centuries.
Almadén is a town and municipality in the spanish province of Ciudad Real, within the autonomous community of Castile-La Mancha. The town is located at 4° 49' W and 38° 46' N and is 589 meters above sea level. Almadén is approximately 300 km south of Madrid in the Sierra Morena. The name Almadén is from the Arabic: المعدن, romanized: al-maʻdin, lit. 'the metal', 'the mineral' or 'lode', and so by extension, the place where these are excavated, 'the mine'. Originally a Roman settlement, the town was captured in 1151 by Alfonso VII and given to the Knights of the Order of Calatrava.
Potosí, known as Villa Imperial de Potosí in the colonial period, is the capital city and a municipality of the Department of Potosí in Bolivia. It is one of the highest cities in the world at a nominal 4,090 m (13,420 ft). For centuries, it was the location of the Spanish colonial silver mint. A considerable amount of the city's colonial architecture has been preserved in the historic center of the city, which—along with the globally important Cerro Rico de Potosí—are part of a designated UNESCO World Heritage Site.
Huancavelica or Wankawillka in Quechua is a city in Peru. It is the capital of the department of Huancavelica and according to the 2017 census had a population of 49,570 people. The city was established on August 5, 1572 by the Viceroy of Peru Francisco de Toledo. Indigenous peoples represent a major percentage of the population. It has an approximate altitude of 3,676 meters; the climate is cold and dry between the months of February and August with a rainy season between September and January. It is considered one of the poorest cities in Peru.
Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals typically oxidise or react chemically at much higher temperatures than base metals. When they are heated at high temperatures, the precious metals remain apart, and the others react, forming slags or other compounds.
Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes. Gold mining produces about 3600 tons annually, and another 300 tons is produced from recycling.
The patio process is a process for extracting silver from ore. Smelting, or refining, is most often necessary because silver is only infrequently found as a native element like some metals nobler than the redox couple 2 H+ + 2 e−⇌ H
2 (gold, mercury, ...). Instead, it is made up of a larger ore body. Thus, smelting, or refining, is necessary to reduce the compound containing the Ag+ cation into metallic Ag and to remove other byproducts to get at pure silver. The process, which uses mercury amalgamation to recover silver from ore, was first used at scale by Bartolomé de Medina in Pachuca, Mexico, in 1554. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas. Although some knowledge of amalgamation techniques were likely known since the classical era, it was in the New World that it was first used on a large industrial scale. Other amalgamation processes were later developed, importantly the pan amalgamation process, and its variant, the Washoe process. The silver separation process generally differed from gold parting and gold extraction, although amalgamation with mercury is also sometimes used to extract gold. While gold was often found in the Americas as a native metal or alloy, silver was often found as a compound such as silver chloride and silver sulfide, and therefore required mercury amalgamation for refinement.
Cerro Rico, Cerro Potosí or Sumaq Urqu, is a mountain in the Andes near the Bolivian city of Potosí. Cerro Rico, which is popularly conceived of as being "made of" silver ore, is famous for providing vast quantities of silver for the Spanish Empire, most of which was shipped to metropolitan Spain. It is estimated that eighty-five percent of the silver produced in the central Andes during this time came from Cerro Rico.
Francisco Álvarez de Toledo, also known as The Viceroyal Solon, was an aristocrat and soldier of the Kingdom of Spain and the fifth Viceroy of Peru. Often regarded as the "best of Peru's viceroys", he is as often denounced for the negative impact his administration had on the Indigenous peoples of Peru.
The Chichimeca War (1550–90) was a military conflict between the Spanish Empire and the Chichimeca Confederation established in the territories today known as the Central Mexican Plateau, called by the Conquistadores La Gran Chichimeca. The epicenter of the hostilities was the region now called the Bajío. The Chichimeca War is recorded as the longest and most expensive military campaign confronting the Spanish Empire and indigenous people in Aridoamerica. The forty-year conflict was settled through several peace treaties driven by the Spaniards which led to the pacification and, ultimately, the streamlined integration of the native populations into the New Spain society.
Matehuala is a city in the Mexican state of San Luis Potosí, situated at an elevation of about 1,500 m. Matehuala is also the municipal seat of the municipality of the same name, located in the northern part of the state, on the border with the southwestern corner of Nuevo León. The municipality of Matehuala has a population of 102,199, and an area of 1,302 km2 (503 sq mi).
Silver mining is the extraction of silver from minerals, starting with mining. Because silver is often found in intimate combination with other metals, its extraction requires elaborate technologies. In 2008, ca. 25,900 metric tons were consumed worldwide, most of which came from mining.
The pan amalgamation process is a method to extract silver from ore, using salt and copper(II) sulfate in addition to mercury. The process was widely used from 1609 through the 19th century; it is no longer used.
The Royal Governor of Panama ruled over the Spanish colonial administrative district known first as the colony of Darién and later as the colony of Castilla de Oro, which in 1529 was renamed Panamá. This district was subordinated to the Viceroyalty of New Granada on August 20, 1739. There were 113 such governors or presidents during the Spanish conquest and the later periods of Spanish-centered colonialism.
Santa Maria del Rio is one of the 58 municipalities that make up the Mexican state of San Luis Potosí. The municipality is located in the southern part of the state, approximately 48 kilometers east of the city of San Luis Potosí. Santa Maria del Rio has a land area of 1,655 square kilometers, with 37,290 inhabitants. As of 2005, 12,000 were living in the town of Santa Maria del Rio. The area is famous for its rebozos, being the cradle of the blue and white rebozo de bolita. The Rebozo Caramelo is woven there.
The economy of Hispania, or Roman Iberia, experienced a strong revolution during and after the conquest of the peninsular territory by Rome, in such a way that, from an unknown but promising land, it came to be one of the most valuable acquisitions of both the Republic and Empire and a basic pillar that sustained the rise of Rome.
The royal fifth is a historical royal tax which reserves to the monarch 20% of all precious metals and other commodities acquired by his subjects as war loot, found as treasure or extracted by mining. The 'royal fifth' was first instituted in medieval Muslim states from interpretations of Qur'an, though the extent to which it applied was debated between schools of Islam. During the age of exploration, Christian Iberian kingdoms and their overseas colonial empires also instituted the tax, though to encourage exploration, some monarchs allowed colonists to keep some or all of the fifth.
The School of Mining Engineering of Madrid is located in calle Ríos Rosas, Madrid, Spain. It is one of the engineering schools of the Technical University of Madrid which was founded in 1971 through the integration of the Higher Technical Schools.
Alonso of Spain was an infante of Spain, who died in childhood.
