Rio Tinto, in the province of Huelva, Spain, has a high content of ferruginous salts and ferric sulphate which, together with the scarcity of oxygen, give a very acidic pH. Characteristic structures are present on the banks resulting from the cooling of slag and mining waste. Hence its incredible chromatic variety.
