| Abstract: | Factors that may influence copper recovery rate including pH, temperature and cuprous ion concentration were studied when using neutralization process to recover copper from spent etching solution, and options to choose the best conditions for precipitating copper were optimized. A clean and effective method to comprehensive utilize mother liquid after recovering copper was introduced as well. |
