Resumen

Conventional hydrometallurgical systems for gold recovery from its ores include the use of cyanide as the leaching agent, followed by adsorption of the Au(CN)2 complex on activated carbon. These processes require that the leaching and recovery systems should be highly alkaline. Gold deposits are also rich in sulphides, which give acidic characteristics to the ores. For these reasons, the search for a suitable lixiviant in an acid environment has been of great interest. The use of thiocyanate as a leaching agent under acidic conditions for gold dissolution and its recovery from solution using activated carbons are presented.
