Río Tinto-Land. Río Tinto rises in the Adre caro’s mountains, in the Huelva’s province in Andalusia. This river is known for its red color because of the minerals: pyrite, chalcopyrite, gossans and bacterium called arqueobacterium that produce microbiological oxidation which transforms the sulfide ions in sulfuric acid bacterium. This cause that the river is acid and it is impossible to remove his spots at all. For every liter of water there are 6 grams of minerals.
The English came to Rio Tinto mines in 1873. A British consortium bought mines to the state and found the RIO TINTO COMPANY LIMITED. To transport the minerals to the port of Huelva from the red mines Huelva appeared building the railroad. This also caused a great social change with the coming of foreign labor from Spain and Portugal. Because of the location of the town of the Red River the production fell, and they had to move to another close territory.
In 1930, Red River reaches its highest production record and since its beginning started to decrease, so in 1954 the state closed mines. After, other companies exploited the land. Today it is a tourist spot visited by many people and groups. Visitants can enjoy an experience in railway and meet the river more closely. You can also visit the mine “Peña de Hierro”, located outside.
