Miners in Latin America, 1573-1820s

From The Other Slavery: The Uncovered Story of Indian Enslavement in America, by Andrés Reséndez (HarperCollins, 2016), Kindle pp. 123-124:

Beyond northern Mexico, coerced Indian labor played a fundamental role in the mining economies of Central America, the Caribbean, Colombia, Venezuela, the Andean region, and Brazil. Yet the specific arrangements varied from place to place. Unlike Mexico’s silver economy, scattered in multiple mining centers, the enormous mine of Potosí dwarfed all others in the Andes. To satisfy the labor needs of this “mountain of silver,” Spanish authorities instituted a gargantuan system of draft labor known as the mita, which required that more than two hundred Indian communities spanning a large area in modern-day Peru and Bolivia send one-seventh of their adult population to work in the mines of Potosí, Huancavelica, and Cailloma. In any given year, ten thousand Indians or more had to take their turns working in the mines. This state-directed system began in 1573 and remained in operation for 250 years. Other mines of Latin America, such as the gold and diamond fields of Brazil and the emerald mines of Colombia, depended more on itinerant prospectors and private forms of labor. But even though the degree of state involvement and the scale of these operations varied from place to place, they all relied on labor arrangements that ran the gamut from clear slave labor (African, Indian, and occasionally Asian); to semi-coercive institutions and practices such as encomiendas, repartimientos, debt peonage, and the mita; to salaried work. Mines all across the hemisphere thus propelled the other slavery.
