Desarrollo de carbones activados magnéticos para la recuperación de oro en soluciones de cianuro

Activated Carbons owe its adsorptive properties to their highly developed porous structure. As a result, activated carbons have extensive specific surface areas. Currently, granular activated carbons produced from coconut shells are widely used for gold recovery from alkaline cyanide solutions. Magnetic activated carbons (MACs) for gold recovery, synthesized from sources different that the traditional ones, have been developed at the University of Utah, mixing a carbon source with a magnetic precursor, and putting the mixture under controlled conditions of temperature and gaseous phase composition. This document contains fundamental aspects and preliminary experimental results during the development of magnetic activated carbons.
