Extraction of Tin (Sn) from Solder Dross by Using Hydrochloric Acid Leaching Treatment

摘要: This project deals with the experimental results of leaching Sn from solder dross by means using different concentration hydrochloric acid (HCl). Solder was sieved to obtain a mean particle size 75 μm. The powder obtained leached HCl aqueous solution. To optimize parameter required for recovery dross, initially bench scale studies were carried out varying concentration, stirring time and temperature. indicate that 98.7% 0.1M HCl, 24 hours at60°C solution
