| [3] For centuries, it was the location of the Spanish colonial silver mint. | WIKI |
| Potosxc3xad lies at the foot of the Cerro de Potosxc3xad[4] xe2x80x94sometimes referred to as the Cerro Rico ("rich mountain")xe2x80x94 a mountain popularly conceived of as being "made of" silver ore that dominates the city. | WIKI |
| The Cerro Rico is the reason for Potosxc3xad's historical importance since it was the major supply of silver for the Spanish Empire until Guanajuato in Mexico surpassed it in the 18th century. | WIKI |
| The silver was taken by llama and mule train to the Pacific coast, shipped north to Panama City, and carried by mule train across the isthmus of Panama to Nombre de Dios or Portobelo, whence it was taken to Spain on the Spanish treasure fleets. | WIKI |
| Some of the silver also made its way east to Buenos Aires, via the Rio de la Plata. | WIKI |

| Located in the Bolivian Tin Belt, Cerro Rico de Potosxc3xad is the world's largest silver deposit and has been mined since the sixteenth century, producing up to 60,000 tonnes by 1996. | WIKI |
| Estimates are that much silver still remains in the mines. | WIKI |
| By 1891, low silver prices prompted the change to mining tin, which continued until 1985. | WIKI |
| At peak production in the sixteenth and seventeenth centuries, the ore contained up to 40% silver. | WIKI |
| Colonial silver boom[edit] | WIKI |
| See also: Real Situado and Global silver trade from the 16th to 18th centuries | WIKI |
| The rich mountain, Cerro Rico, produced an estimated 60% of all silver mined in the world during the second half of the 16th century. | WIKI |
| Potosxc3xad miners at first mined the rich oxidized ores with native silver and silver chloride (cerargyrite) that could be fed directly into smelting furnaces. | WIKI |
| But by 1565, the miners had exhausted the direct-smelting ore, and silver production plummeted. | WIKI |
| Silver production was revived by the introduction of the patio process, invented in Mexico in 1554. | WIKI |
| The patio process used mercury amalgamation to extract silver from lower-grade ores, and those containing silver sulfide (argentite), as was typical of the unoxidized ores found deeper in the mountain. | WIKI |
| Spanish American mines were the world's most abundant sources of silver during this time period. | WIKI |
| Spanish America's ability to supply a great amount of silver and China's strong demand for this commodity resulted in a spectacular mining boom. | WIKI |
| The true champion of this boom in the silver industry was indeed the Spanish crown. | WIKI |
| Indigenous laborers were required to work in Potosxc3xad's silver mines through the Spanish mita system of forced labor, based on an analagous mit'a system traditional to pre-Hispanic Andean society (though the mit'a directed labor for public works and collective agricultural projects). | WIKI |
| The largest sector of the population were native men, forced to labor underground mining the silver ore, but there were considerable opportunities for merchants and native traders, who became wealthy. | WIKI |
| According to legend, in about 1462, Huayna Capac, the eleventh Sapa Inca of what by then was known as the Inca Empire "set out for Ccolque Porco and Andaccaua, the location of his mines from which were taken innumerable arrobas of silver" (an arroba is a Spanish unit of weight equivalent to approximately 25 pounds (11xc2xa0kg)). | WIKI |
| "This doubtless must have much silver in its heart"; whereby he subsequently ordered his vassals to go to Ccolque Porco ... and work the mines and remove from them all the rich metal. | WIKI |
| They did so, and having brought their tools of flint and reinforced wood, they climbed the hill; and after having probed for its veins, they were about to open those veins when they heard a frightening thunderous noise which shook the whole hill, and after this, they heard a voice which said: "Do not take the silver from this hill, because it is destined for other masters." | WIKI |
| It and its region prospered enormously following the discovery of the New Worldxe2x80x99s biggest silver lodes in the Cerro de Potosxc3xad south of the city. | UNESCO |
| The major colonial-era supplier of silver for Spain, Potosxc3xad was directly and tangibly associated with the massive import of precious metals to Seville, which precipitated a flood of Spanish currency and resulted in globally significant economic changes in the 16th century. | UNESCO |
| The Cerro de Potosxc3xad reached full production capacity after 1580, when a Peruvian-developed mining technique known as patio, in which the extraction of silver ore relied on a series of hydraulic mills and mercury amalgamation, was implemented. | UNESCO |
| The industrial infrastructure comprised 22 lagunas or reservoirs, from which a forced flow of water produced the hydraulic power to activate 140 ingenios or mills to grind silver ore. | UNESCO |
| Criterion (iv): Potosxc3xad is the one example par excellence of a major silver mine in modern times. | UNESCO |
| The industrial infrastructure comprised 22 lagunas or reservoirs, from which a forced flow of water produced the hydraulic power to activate the 140 ingenios or mills to grind silver ore. | UNESCO |
