This process has been applied in metallurgy, to recover metals from dilute leach liquors [13-18]. It is also exploited in metal finishing industry to recover noble metals such as copper from some waste solutions, etc. This article is concerned with the study of copper cementation
Optimization of copper cementation process by iron
15/09/2007· The present study is undertaken to investigate the effectiveness of process variables, namely: initial copper concentration, temperature, pH and flow rate on the copper cementation yield of a laboratory-scale tubular reactor containing volumetric electrode of iron.
