Laboratory equilibrium tests are recommended to determine extraction efficiency, copper selectivity, and phase separation performance under actual operating conditions. Proper pH control helps optimize copper transfer while minimizing impurity loading, supporting stable operation of SX-EW plants processing complex copper resources.

Q2. How selective is PANDA984N mixed oxime extractant for copper extraction from high chloride, high magnesium, and high iron solutions?

PANDA984N mixed oxime extractant is designed to provide selective copper extraction in hydrometallurgical systems containing various dissolved impurities. In high chloride, magnesium, or iron-containing solutions, extraction behavior depends on solution chemistry, oxidation state, acidity, and impurity concentration. The combined aldehyde oxime and ketoxime formulation provides a balance between copper extraction strength and selectivity. Before industrial application, laboratory testing should be conducted to evaluate copper distribution coefficient, iron rejection, phase disengagement characteristics, and stripping performance. Proper circuit design, including scrubbing and process control, can further improve copper purification efficiency in challenging leach environments.

Q3. How does the aldehyde oxime and ketoxime ratio in PANDA984N affect copper extraction and iron separation performance?

The ratio between aldehyde oxime and ketoxime components in PANDA984N mixed oxime extractant influences important solvent extraction properties, including copper loading capacity, extraction kinetics, selectivity, and impurity rejection. Aldehyde oxime components generally contribute strong copper extraction capability, while ketoxime components can improve operational balance and phase behavior. The optimal formulation depends on the specific copper leach solution, including copper concentration, ferric iron level, acidity, and operating temperature. Metallurgical laboratories typically evaluate different extractant formulations through equilibrium tests and McCabe-Thiele analysis to identify suitable conditions for achieving efficient copper recovery and effective iron separation.

Q4. What factors influence the copper loading capacity and stripping performance of PANDA984N in SX-EW operations?

The copper loading capacity of PANDA984N mixed oxime extractant is affected by extractant concentration, organic formulation, copper concentration in the aqueous phase, equilibrium pH, temperature, and diluent properties. During stripping, sulfuric acid concentration, phase ratio, and contact time determine copper transfer from the organic phase into the electrolyte. Industrial SX-EW plants normally optimize extraction and stripping conditions through laboratory testing and continuous monitoring of copper concentration, organic activity, and phase behavior. Maintaining a proper balance between loading capacity and stripping efficiency is essential for stable copper production and consistent electrolyte quality.

Q5. What sulfuric acid concentration and temperature conditions are suitable for stripping copper loaded by PANDA984N extractant?

Copper stripping from PANDA984N-loaded organic phase is typically performed using sulfuric acid electrolyte under controlled conditions suitable for downstream electrowinning. The required acid concentration and temperature depend on copper loading level, organic composition, electrolyte specifications, and plant operating conditions. Excessively aggressive stripping conditions may affect organic stability, while insufficient stripping strength may reduce copper transfer efficiency.
