  • Recycling of Printed Circuit Boards IntechOpen

    Recently a modified pyrometallurgy to recover metals from PCBs has been proposed (Zhou et al. 2010) showing that addition of 12 wt. NaOH as slag-formation material promotes the effective separation of metals from slag the remaining slag in the blowing step was found to favour the separation of Cu from other metals and allow noble metals to enter the metal phase to the greatest extent.
