Firstly, the raw fly ash was crushed (≤ 100 mesh) and the iron was removed through magnetic separation (iron level ≤ 1 wt%). Subsequently, the pretreated sample was dissolved in hydrochloric acid (20–37 wt%) to obtain leachate (pH = 1–3, Ga present as [GaCl 4] −). Ga in the leachate was then adsorbed with a macro-porous cationic resin.
