  • TITLE: Recycling of Electronic Waste, Using Basic and Acid Leaching

    AUTHORS: Miguel Aguilar Cortes, Martha Lilia Domínguez Patiño

    KEYWORDS: TCI, Acidic and Basic Leaching and Electronic Waste

    JOURNAL NAME: Open Journal of Applied Sciences, Vol.6 No.3, March 30, 2016

    ABSTRACT: This recycling of printed circuit board (TCI) for the production of metals, given the environmental degradation that can cause toxic substances of these, is the reuse of valuable materials recovered from the TCI, this being an economic engine that promotes the recycling of this waste. This paper presents a methodology for evaluating the reaction kinetics and leaching of metals that form the metal substrate, which have environmental and energy advantages, so the generation of new recovery techniques metals from the TCI low environmental and energy impact is increasingly necessary, for it is essential to establish the parameters affecting the reaction rate and identify design alternatives to determine whether or not sustainable, economically viable and that does not pollute. The method adopted was a leaching acid samples, where the full factorial method employed two experimental levels to evaluate the influence of: leaching time, temperature of the aqueous leach solution, reaction kinetics and solid/liquid, on the percentage of metal extraction. Subsequently, the metals are obtained by calcining and smelting the resulting salts by addition of acid liquor.
