CABALLERO, Erich; SANCHEZ, Wilson  and  RIOS, Carlos A.. Synthesis of geopolymers from alkaline activation of gold mining wastes. Ing. compet. [online]. 2014, vol.16, n.1, pp.317-330. ISSN 0123-3033.

This paper reports preliminary results related to the development of inorganic polymers (geopolymers) from alkaliactivation of gold mining wastes. Mineralogical and physicochemical characterization of these gold mining wastes shows their significant potential as geopolymeric source precursors as a reasonable alternative to the development of alkali-activated friendly environmental binders. Geopolymerization process is a viable way to transform these residues in materials with high mechanical strength, high chemical inertness and high durability over time, giving add value to the by-products of the mining industry

Keywords : Alkaline activation; environmental geology; geopolymers; mining products.
