Tumbaga is the name given by Spanish Conquistadors for a non-specific alloy of gold and copper, and metals composed of these elements. Pieces made of tumbaga were widely found in pre-Columbian Mesoamerica in North America and South America. The term is a borrowing from the Tagalog tumbaga. This came from Malay tembaga, meaning 'copper' or ...
32 of these have names tied to the Earth and the other 10 have names connected to bodies in the Solar System. The first tables below list the terrestrial locations (excluding the entire Earth itself, taken as a whole) and the last table lists astronomical objects which the chemical elements are named after.

41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
During and after the Conquest, the working of the metal by the indigenous was disrupted. Many of the villages of the Pátzcuaro area were abandoned in large part due to the abuses by conquistador Nuño de Guzmán. The Spanish were soon aware of the copper deposits of this region and the indigenous’ ability to work it.
Production trends in the top five copper-producing countries, 1950-2012. This is a list of countries by mined copper production. Copper ore can be exported to be smelted so that a nation's smelter production of copper can differ greatly from its mined production. See: List of countries by copper smelter production.
An estimated 80% of all copper ever mined is still in use today. [46] In volume, copper is the third most recycled metal after iron and aluminium. [47] As of 2023, recycled copper supplies about one-third of global demand. [48] The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps.
In the period up to the end of World War I (1914–18) the copper was mostly extracted by labourers from Spain and shipped to the United States. Companies active in the mines were La San José Copper Mines and Ferrocarril del Cobre, The Copper Mines, Copper Company and the Cuba Leasing Company. After the war, operations were greatly reduced.
For the New Spanish, America was a new land to explore for gold and silver and also to spread Christianity. The New Spanish named the people they encountered "Tarahumara", derived from the word Rarámuri, which is what the indigenous people call their men. Some scholars theorize that this word may mean 'The running people'.
