Francisco Sanz, principal Administrator of the Mines , obta i ned a supply of seeds from Niebla and sowed them broadcast. Today , you can see the development of a fine pine grove from which, some day , the wood will be used for construction and fo r the mine rs.

The artificial cementation process produced copper relatively cheaply from low copper content pyrites . There were a number of disadvantages to its use at Rio Tinto and Rua Figueroa listed them as follows: A considerable amo unt of fuel wood was required . All the s ulphu r in the are was lost. It was diffic ult to roast teleras uniformlYi some or e was over roasted , some not roasted at all . Soluble cop per was lost during the - 35 - rainy season. Sulphur dioxide emissions killed the vegetation.
Copper for munitions. At conside rable risk to all involved , most of the copper at the mines was sent to Cadiz, for some time the only bastion holding out against the French . It was 1814 before any further production of copper precipitate and a further 10 years before smelting r estarted in 1824. Jose Martinez succeeded Letona as administ rator in 1825 and about this time the Planes smelti ng furnaces were rebuilt c l oser to the village of Rio Tinto , alongside the Rio Agrio, upstream of its junction with the Tinto river .
