Mechanism and Clean Procedure to Extract Gold from
2016-1-1 Abstract. The recoveries of gold from printed circuit board are carried out in this work. Chemical analysis of waste printed circuit board was determined by ICP (Inductively Coupled Plasma) method. The dissolving mechanism of gold was elaborate. The thermodynamics for leaching process of gold was analyzed, the E-pH diagrams at 298K were drew by
