Pueblo Viejo Mine
The Pueblo Viejo mine is a gold mine located in the north-central region of the Dominican Republic in the Sánchez Ramírez Province. It is the largest gold mine in Latin America and fifth largest in the world. It is also the first exploited mine by the Spaniards in America. The mine produced 581,000 ounces of gold in 2018 and 6.55 million ounces of gold in reserve. The mine, run by the Pueblo Viejo Dominicana Corporation, is 60% owned by Barrick Gold and 40% owned by Newmont Goldcorp Newmont Corporation is a gold mining company based in Greenwood Village, Colorado, United States.

Cotuí
Cotuí is a city in the central region of the Dominican Republic and is one of the oldest cities of the New World. It is the capital of Sánchez Ramírez Province in the Cibao. According to the Population and Housing Census, the municipality had a total urban population of 79,596 inhabitants. History It was founded in 1505 by Rodrigo Trillo de Mejía for order of Nicolas de Ovando, who was the governor of Hispaniola. Its name, formerly written Cotuy, was the name of the Taino community located around the gold and silver mines exploited by the Spanish conquerors from the first decade of the 16th century. Early years The total sum of gold extracted during the first two decades of the 16th century in the Spanish Island was estimated at 30,000 kilos, an amount greater than the totality of production in Europe in those years and above the total gold collected by the Portuguese in Africa.

Dominican Republic
The Dominican Republic ( ; es, República Dominicana, ) is a country located on the island of Hispaniola in the Greater Antilles archipelago of the Caribbean region. It occupies the eastern five-eighths of the island, which it shares with Haiti, making Hispaniola one of only two Caribbean islands, along with Saint Martin, that is shared by two sovereign states. The Dominican Republic is the second-largest nation in the Antilles by area (after Cuba) at , and third-largest by population, with approximately 10.7 million people (2022 est.), down from 10.8 million in 2020, of whom approximately 3.3 million live in the metropolitan area of Santo Domingo, the capital city. The official language of the country is Spanish. The native Taíno people had inhabited Hispaniola before the arrival of Europeans, dividing it into five chiefdoms. They had constructed an advanced farming and hunting society, and were in the process of becoming an organized civilization. The Taínos also in ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cibao
The Cibao, usually referred as "El Cibao", is a region of the Dominican Republic located at the northern part of the country. As of 2009 the Cibao has a population of 5,622,378 making it the most populous region in the country. The region constitutes a "developed macro-region"; with a large industrial base and high levels of progress among its inhabitants, it has the highest levels of education and the highest quality of life among the three main regions of the Dominican Republic. Cibao is social-culturally characterized by the overwhelming predominance of the European legacy in the island, and economically for being the most prosperous region in the country. Etymology The word Cibao, ; , means "place where rocks abound". Cibao was a native name for the island, although the Spanish used it during the Spanish conquest to refer to the rich and fertile valley between the Central and Septentrional mountain ranges. Geography and economy El Cibao occupies the central and northern par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pressure Oxidation
Pressure oxidation is a process for extracting gold from refractory ore. The most common refractory ores are pyrite and arsenopyrite, which are sulfide ores that trap the gold within them. Refractory ores require pre-treatment before the gold can be adequately extracted. The pressure oxidation process is used to prepare such ores for conventional gold extraction processes such as cyanidation. It is performed in an autoclave at high pressure and temperature, where high-purity oxygen mixes with a slurry of ore. When the original sulfide minerals are oxidized at high temperature and pressure, it completely releases the trapped gold. Pressure oxidation has a very high gold recovery rate, normally at least 10% higher than roasting. The oxidation of the iron sulfide minerals produces sulfuric acid, soluble compounds such as ferric sulfate, and solids such as iron sulfate or jarosite. The iron-based solids produced pose an environmental challenge, as they can release acid and heav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
