The solution is fed to the fixed bed column, contacting with resins. This process is usually comprised of two steps: the saturation is carried out with the ionic solution; and elution, which removes ions from the resin, using NaSCN or NaNO 3, producing a purified gold solution (Bachiller et al., 2004; García et al., 2014).
