The leaching rate of copper was greatly affected by current density and agitation speed. Increasing agitation and lowering current density enhanced utilization efficiency of electro-generated chlorine for copper leaching. The leaching of copper up to 98 % was achieved at 20 mA/ cm2, 50 ℃, 180 minutes, and 600 rpm in 1 M HCl solutions.
In this study, a electrochemical-chemical combined dissolution technology was conducted by electro-generated chlorine to obtain ruthenium solution from ruthenium metal. To find out the optimum leaching conditions of ruthenium in chloride solution, this leaching process was carried out on the variation of pH, reaction time, temperature and applied voltage at the electro-generated chlorine ...

01-01-2010· Based on the results of the leaching experiment, the leaching of copper by electro-generated chlorine is proposed to proceed through three stages: stage I (ORP of leach solution ≈ 1300 mV SHE), stage II (380 mV SHE < ORP < 490 mV SHE), and stage III (ORP > 490 mV SHE).
MCLE (Matte Chlorine Leach and Electro-winning) process developed by Sumitomo Metal Mining Co., LTD. is well known as a unique commercial nickel refining process with high nickel recovery ratio. Two types of nickel sulfide, nickel matte and mixed sulfide (MS: mixture sulfide of nickel and cobalt), are treated in the MCLE process, and the leaching rate difference for each materials become ...
