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.
At peak production in the sixteenth and seventeenth centuries, the ore contained up to 40% silver.
The ore deposits reside in veins present in the dacite volcanic dome.
Hydrothermal circulation and fracturing soon followed, altering the dacite and depositing ore minerals and gangue in the veins.
But by 1565, the miners had exhausted the direct-smelting ore, and silver production plummeted.
While more skilled laborers extracted the ore, mitayos were tasked with carrying it back to the surface in baskets, leather bags, or cloth sacks.
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.
They gathered in a confederation opposed to another one, the Vicuxc3xb1as, a melting pot of natives and non-Basque Spanish and Portuguese colonists, fighting for control over ore extraction from the mines and its management.
Another explanation, given by several Quechua speakers,[specify] is that potoq is an onomatopoeic word that reproduces the sound of the hammer against the ore, and oral tradition has it that the town derived its name from this word.
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.
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.
The ground ore was amalgamated with mercury in refractory earthen kilns, moulded into bars, stamped with the mark of the Royal Mint and taken to Spain.
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.
The ground ore was then amalgamated with mercury in refractory earthen kilns called huayras or guayras.
