Mercury mining in Spain

Excellent article from wikipedia on the mercury* deposits of Almadén which account for the largest quantity of liquid mercury metal produced, historically, in the world. Some points: * (mercury = mercurio; cinnabar = cinabrio in Spanish)

  • Approximately 250,000 metric tons of mercury have been produced in the Almadén mines in the past 2,000 years. It is the "oldest" and largest mercury mine in the world.
  • Almadén is home to the world's greatest reserves of cinnabar , a mineral from which mercury is extracted. Cinnabar was first used for pigment by the Romans. Later, the mineral was used mostly in medicine and alchemy during the Arab domination of Spain.
  • the King of Spain agreed to send 30 prisoners to serve their sentences as laborers at Almadén. The number was increased to 40 in 1583 . The prisoners, known as forzados , were selected out of criminals waiting for transport to the galleys in the jail of Toledo . Those selected usually had limited sentences and good physical abilities. Murderers and capital criminals were rarely selected, as the galleys were considered a far harsher punishment than the mines of Almadén. This assumption would later prove false when the horrors of mercury poisoning were discovered.
  • he penal establishment at Almadén was closed in 1801 . In 1916 , a special council was created to operate the mines, introducing new technology and safety improvements. A record production of 82,000 mercury flasks was reached in 1941 , just after the Spanish Civil War .
  • The price for mercury decreased from a peak of 571 US$ in 1965 to 121 US$ in 1976 making economically planing difficult.
  • In 1981 , the Spanish government created the company Minas de Almadén y Arrayanes to operate the mine.
  • In 2000 , the mines closed due to the fall of the price of mercury in the international market, caused to the fall of its demand. However, Almadén still has one of the world's biggest reservoirs of mercury. A museum has been built, including visit to the mines (areas from 16th to 20th century). Read

  • The Mariscal mine at Almaden (good, short article) " Mercury became very  valuable because of its use in the amalgamation process used to remove  gold and silver in the Americas. Almadén developed into an important  mining and industrial city, and contributed major resources to the Spanish expansion in the Americas. During the 16th and 17th centuries,  the mine belonged to German bankers who introduced numerous innovations. Most of produced mercury, was sent to Seville, from where it embarked to America."
