Copper Solvent Extraction Electrowinning Process Modelling

Dynamic modelling of an industrial copper solvent

1/1/2006 The copper leaching, solvent extraction and electrowinning (LX/SX/EW) process is one of the most important options in the production of copper from low-grade oxidized ore. Research on the copper LX/SX/EW process has so far mainly focused on the process equipment and control of the plants relies on basic control loops.

Dynamic modelling of copper solvent extraction

1/12/2009 The copper Leaching, Solvent Extraction and Electrowinning circuit (LX–SX–EW) is one of the most effective processes for extracting copper from low grade ores. This work focuses on the liquid–liquid extraction SX sub-process, since many difficult to handle operational problems within LX–SX–EW circuits are related to SX malfunction.

Control of an industrial copper solvent extraction process

1/1/2009 The copper leaching, solvent extraction and electrowinning (LX/SX/EW) process is one of the most important methods in the production of copper from low-grade oxidized ore. Research on the copper LX/SX/EW process to date has focused on the process chemicals and equipment, and control of the industrial plants relies on simple PID control loops and manual tuning.

Copper electrowinning: theoretical and practical design

For direct or post solvent extraction copper electrowinning design, key theoretical considerations include current density and efficiency, electrolyte ion concentrations, cell voltages and electrode overpotentials, physical cell dimensions, cell flow rates and electrode face velocities, and electrolyte
