Abstract Scope This paper presents a novel methodology to recover gold from waste solutions of printed circuit boards (PCBs) generated during the gold electro-plating. Studies have been carried out using two different sizes of hydrocyclone (339.06 mm and 357.14 mm height) at various parameters such as current, flow rate, electrolyte concentration, cathode materials, and anodic area to recover the gold. ~96% gold was recovered using short-corn type hydrocyclone (339.06 mm) at following conditions: applied current 17.4A, flow rate 3.98m/s, using stainless steel as cathode material. However, approximately same amount of gold can be also recovered with long-corn type hydrocyclone (357.14 mm). But, the possibility for damage of long-corn type hydrocyclone might be higher than short corn type hydrocyclone because reaction occurs only at small reaction surface area during gold recovery. Therefore, short corn type hydrocyclone has been considered for further study to recover gold.
